Precautions Against Germ Hazards
1) When it is necessary to touch the equipment, options and/or other peripheral devices at a customer
who uses intracorporeal (transesophageal, transurethral, transvaginal, transrectal) probes that need
sterilization, take special care to protect your hands against germs, irrespective of the usage of the
equipment: whether it is used in the operation room or not.
2) Service tools are subject to germ pollution in hospitals and, therefore, need periodical sterilization.
3) Be careful not to directly touch anything assumable to have germ pollution. If necessary, ask the
customer for effective protection against germs.
4) Be sure to confirm the equipment, options and peripheral devices are washed, disinfected or
sterilized appropriately when you take them back from customer site.
5) In case the equipment radiates X-ray, pay attention to the circumference and take care not exposed
X-ray indiscreetly when the equipment is radiating. You must put a film badge for monitoring the
personal exposure at proper position when you do the repair work.
Whenever grease, oil or other chemicals is used for maintenance service, options and/or peripheral
devices, be sure to clean the equipment and/or devices after service work.
1-8
Precautions to ensure safety of software
OS (Operating System, such as Windows) operation is allowed Service Engineer who has taken
appropriate training. Illegal change on OS or our program files, Illegal copy of file/folder/partition
which NOT instructed, are prohibited.
Computer controlled medical equipment that involves starting up an operating system from an internal
storage drive could become infected with computer viruses.
Such equipment is usually infected via peripheral storage, media or connections to a network.
Examples detailing route of infection
A) Infections caused during upgrades or maintenance by service engineer.
An infected USB memory device was connected.
An infected floppy diskette was inserted.
A virus-infected USB hard disk drive was connected to remove data.
B) The end user connected an infected USB memory device for presetting, backing up images or
copying.
An infected floppy diskette was inserted.
A virus-infected USB hard disk drive was connected to remove data.
1) Scan all media for viruses before connecting them to or inserting them in the equipment.
2) When an infection is detected, investigate the route of infection and its scope before removing the
virus.
3) Any connections to a network should as far as possible be routed via a firewall.
4) Software, files or services other than those designated by us must not be installed on or uninstalled
from the equipment. Nor must files other than those specified by us be modified or edited.

Chapter 1 Introduction
Precautions for software safety of maintenance tools
1-9
These maintenance tools refer to the laptop computers and auxiliary storage devices that service
engineers carry around. (Any computer used for creating CD-Rs for installing upgrades is also regarded
as a maintenance tool.) Thus maintenance tools will include laptop computers, floppy diskettes, USB
memory devices, external hard disks, CD-Rs, etc.
1) Perform a virus scan of any tool that will be used to ensure that they are not infected by computer
viruses.
Regularly perform virus scans of maintenance tools.
2) In unavoidable cases when for some reason safety cannot be confirmed, or when an unknown
computer or memory device is connected, be sure to perform a virus check after use.
3) Update with the most recent virus pattern data prior to performing a virus scan.
4) If a virus scan does not remove the cause for anxiety, use another virus scanner to check.
1-10
Precautions regarding handling of patient data
Extreme care must be taken to ensure that data (image data, patient database, DICOM communication
log files) that has been saved to another media during equipment repair and may include patient data is
guarded against leakage, loss and theft. Delete any data that is no longer needed.
1) Work involving use of patient data should be performed in a room that can be locked to prevent
leakage, loss or theft of such data.
2) Such data must be stored in a locked shelf or similar container.
3) If no lockable shelves are available, encrypt the files to reduce possible harm in the event of theft,
leakage or loss.
1-11
Preparation to be made before visit customer
1) When called by a customer on the telephone, note the followings:
• Name of equipment
• Serial number of equipment
• Name of hospital
• Telephone number
• Name of person in charge
• Detail of trouble symptom as far as possible
• State of connection to optional devices
2) Go over the “Technical Bulletin” and “Technical Notes” to see whether the complained trouble can
be mended by means of regular repairing method.

4)
Check for trouble symptoms.
Check for connection to optional devices and other peripheral devices.
Record structure of the equipment such as Software Version.
After working, restore the equipment according to the above mentioned contents of memory if
necessary.
5) After completion of work, put back the peripheral devices to the original condition.
1-13
Handling of PCB
It is our policy that neither repair nor modification of PCBs used for S.M.D. is made in the field as a
rule because of the following reasons:
[REMARKS]
PCB does not need repairing or modifying in the field as a rule.
When handling a PCB, do not touch the IC unless it is necessary.
IC soiled with worker’s hands may cause corrosion. Additionally, foreign particles such as fine solder
dust could be the cause of short-circuited IC lead wires whose pitch is smaller than that of the traditional
ones.
Do not give excessively large shocks to the PCB.
Very thin wiring patterns require extreme care in handling of the PCB.
When replacing the ROM (Read Only Memory) on the PCB, attempting to force the ROM into its
socket would cause the PCB to be subjected to an undue force.
Reuse of chip devices (including resistors, capacitors, diodes, etc.) is strictly inhibited.
z CAUTION z When handling a PCB, avoid touching the IC and connector pins on the devices

About RoHS Directive
RoHS(Restriction of Hazardous Substances) Directive was adopted in Feb 2003 by European Union. It
is closely related to WEEE Directive. This directive restricts the use of hazardous materials in various
type of electronic and electrical equipment.
The PCBs (printed circuit boards) inside and other parts use lead-free (Pb free) solder and lead-free
RoHS compliant components.
Principally it is prohibited to do remodeling or adaptation on PC board, except when there is instruction
by Aloka. Use lead-free solder for soldering internal boards, components and cables.
Do not use old solder that contains lead. It has a different melting point from lead-free solder and must
not be used.
9 Melting point
Eutectic solder
Lead free solder
around 183 Celsius
around 217 Celsius depends on content ratio
Use the label shown above for products
containing only RoHS compliant mounted
components that are soldered using lead-free
solder

Transmission and Reception block
The transmission and reception block consists of:
One PSEL board (probe connector and STCW/Independent receivers)
One TXRX board (transmission, preamplifier)
One RXBF board (Digital Beam Former, RF processor part)
One SERVO board(Control for TEE probe) as Option
z Probe Connector
It is a board that has connectors for electronic probes (electronic sector, electronic linear and
electronic convex). By installing the optional unit EU-9145 on this board (PSEL board), it
can respond also to the Independent probe connection.
The PSEL board is not equipped with HVS (High-voltage switch) that selects the elements
of transmission/reception (simultaneous excitation elements) from all elements of the linear
and convex probes, but the TXRX board is equipped with HVS. In addition, the HVS block
on the TXRX board connect the 96 transmission/reception circuit to 192 channels on PSEL
board with multiplexer.
This board also supports both parallel and serial probe code.
z Transmitters
The transmitters consists of the FPGA block that generates the square wave transmission
trigger signals and the other block that generates the square wave pulse by use of custom IC
excursively for the transmission that consists of FET arrays for ultrasound transmission and
it’s driver circuit (same as ALPHA6).
The data for transmission trigger and transmission focus are stored as parameter data for
each probe on the HDD. These pieces of data are calculated in succession by software based
on the transmission conditions, such as mode, before being sent to the memory on the
TXRX board. Then, the transmit waveform data that is invoked from the memory is delayed
for the transmit focus, then make it as bipolar square wave transmission triggers for 96
channels.
On the other hand, the high-voltage for transmission amplifiers is generated at the
transmission high voltage circuit on RXBF board. +/-90V from the power supply board is
converted to +/-80V (Max. +/-7.5V for CW Doppler) on this circuit and then provide to
TXRX board. On the TXRX board, the square wave transmission pulse is generated in
accordance with square wave transmission triggers, amplified by the transmission voltage
and output a transmit signal.
For the transmission of STCW, a square wave transmission triggers is repeatedly read to
transmit a continuous wave. The transmission voltage is generated for only STCW at the
transmission voltage circuit on the RXBF board, and then provide to the TXRX board as
well. In addition, the transmission for Independent probe uses same circuit as STCW.
z Pre AMP
48 channels of continuation or one jump are chosen from the all 96 channels received
signals in the TXRX board. Then, this signals is amplified by a LNA (low noise
preamplifier) in the PreAMP IC and further amplified by a VGA (Variable Gain Amplifier)
in same IC to match the input level of the S/D in the initial stage of the Digital Beam Former,
and sent to the Digital Beam Former part.

MN2-2064 Rev.0
Chapter 4 System Overview
z STCW Rx, Independent Rx
The STCW reception signals are added to 8 groups according to the degree of beam angle
with a cross-point switch after amplification in the Pre AMP on the PSEL board. Then, it
goes through the quadrant detector, summed with a phase adjusted received signal,
converted to digital signals, and sent to the RXBF board.
The Independent reception signals are amplified by exclusive Pre AMP on the PSEL board,
then go though the quadrant detector and A/D converter with using one channel of STCW
reception circuit, and then sent to the RXBF board.
z Transesophageal probe control (Option)
The SERVO board has a A/D converter for the position detection circuit of transesophageal
probe.
z Digital Beam Former
The analog received signals of 48 channels that are sent from the Pre AMP on the RXBF
board are converted to digital signals. Then, the data of each channel is delayed in the digital
beam former on the same RXBF board accordance with Rx focus data before being
summed.
¾ Delays are digitally processed (e.g., the reading of the dual port memory in the FPGA
on the RXBF board). This makes it possible to continuously varying accurate delays
(continuously varying of received focus points). The digital beam formers have a
function that continuously changes the weighting in the reception circuit for each
channel (reception apodization). This makes the reception beams sharper.

The signals that are handled by the digital beam formers are digital data that allows
parallel processing in a time-shared manner to improve frame rate.
Delayed and summed reception data is sent to the RF Processor part on the same RXBF
board.
z RF Processor
The delayed and added reception signals that sent from the Digital Beam Former part on the
RXBF board performs the ePHD processing, filter processing, pulse inverter process and
interpolation processing in the RF Processor part before being sent the signal as Line data to
the Backend part.
In addition, the RXBF board consists following functions.
¾ Transmission reception timing and control signal generator
¾ Transmission voltage monitoring
¾ Interface of Physio signal, R-trigger generator

Backend block
The Backend block consists of:
One Backend unit EU-9142 equipped with following module,
・One COM Express module (CPU that controls the entire ultrasound diagnostic system)
・One DPM board (Beam Processor)
・One IBP board
(Carrier board equipped with COM Express module and DPM board,
and has following functions:
Interface for Front-End part, Video signal processor and it to the
monitor, interfaces to peripheral devices)
Unlike conventional ultrasound equipment, the function until the ultrasound reception data
(RF/IQ data) which provides from Front-end part displays on the monitor, is processed by
firmware and software.
z Front-End Interface (FEI) part
The FEI preprocesses the reception beam data from the Front-end part by the beam type,
and stores these to the large-capacity memory by the data type. If the stored data size
reaches the predefined data size, then it is transferred to the DPM board via the DPM local
bus.
The FEI is connected with the Front-end via the CPU local Bus, and thus the application
program of the equipment access the register space in the Front-end via the FEI. The
information mapped in the register of the FEI includes footswitch monitoring, Physio Amp
control, heart rate information, and revision information of the mother board and the power
supply module. The application program of the equipment controls them via the FEI.
z BW Process part
In “BW process” processed with firmware on the DPM board, it performs the detection, Log
compression, AGC, Relief, Contrast and so on for the RF signals transfer from the FEI.
Then the following processing is additionally performed.
¾ Smoothing:
Three adjacent ultrasound lines are correlated at the same depth of
pixel. It makes lateral connection smooth, and reduces noise.
¾ AIP:
The spatial processing in several ultrasound lines are performed for
structure detection, boundary enhancement and speckle noise
reduction.
¾ Spatial Compound:
Several transmission/reception frames with different steered angle are
compounded, and moving average processing is performed. This
reduces the ultrasound beam angle-dependent artifacts such as side
lobe, multiple reflections, acoustic shadow and a speckle noise.
¾ Frame Correlation:
The previous and next ultrasound frames are correlated at the same
position of pixel. It makes the image smooth in the time direction, and
reduces noise.
Finally, the attribute information such as data type, time stamp, beam number and so on are
added, and then sent the data to Cine Process part via DMA buffer.

MN2-2064 Rev.0
Chapter 4 System Overview
z Dop Process part
In “Dop process” processed with firmware on the DPM board, it receives the data which is
processed by quadrant detection, filtering and data addition within the sample gate(for PW
Doppler) in the Front-end via FEI, and then performs the filter process for wall motion
rejection, frequency analysis by the FFT and Doppler audio generation.
After frequency analysis, the spectrum is performs the frequency direction averaging, time
direction averaging, Log compression, Contrast and Gray scale mapping(compression). For
both spectrum and audio, the missing signal estimation (MES) process is performed in the
B(F)/D simultaneous operation mode.
Finally, the attribute information are added to the spectrum data, and then sent the data to
Cine Process part via DMA buffer. The Doppler audio data is sent to the Audio Process via
DMA buffer.
z Col Process part
In “Col process” processed with firmware on the DPM board, it receives the data which is
processed by quadrant detection, filtering in the Front-end via FEI, and then several
reception signal according to the color average setting are passed through the wall filter (for
wall motion rejection). Then velocity, variance, Power and eFlow data are calculated with
using the velocity information and Doppler signal intensity that are obtained by velocity
auto correlation between current data and data having the same depth sent one time before.
Because of wideband transmission for eFlow, the filter for wall motion rejection is
adaptively changed to maintain the sensitivity at low-velocity range. After auto-correlation,
vector interpolation is executable to improve the frame rate while maintaining the resolution.
The processed data is first passed through the clutter and noise rejection, and then the
following processing is additionally performed.
¾ Smoothing:
Smoothing consists of the following processes:
• Color Smoothing
Recognizes spatial patterns by several US lines, reduces missing data of
blood flow and rejects noise.
• Line Smoothing
Executes 3-line smoothing by use of data having the same US line depth to
smooth the horizontal connection.
• Pixel Smoothing
Executes smoothing in the direction of the US line depth to smooth the
connection in the depth direction.
• Spatial Smoothing
Executes spatial smoothing by use of several US lines to smooth the data
spatially.
¾ Flow Edge:
Reduces extrusion out of blood vessel by use of tissue data and blood
flow data.
¾ Frame Correlation:
Correlates data between frames and smoothes the connection in the
time direction to reject noise.
Finally, the attribute information are added, and then sent the data to Cine Process part via
DMA buffer.

z Physio Process part
Changes the Physio signal data (including ECG and timescale information) provided from
FEI to a graph data, and then sent the data to Cine Process via DMA buffer.
z Cine Process part
Though conventional machines have processed the data on a hardware basis, this machine
processes the data by the software (software back-end).
Receives the frame data or the line data from the DPM board by DMA transfer, and stores it
in the Cine memory. The Cine memory is retained as a dedicated area in the main memory
on the COM Express module. The retained areas and the storage capacities are as listed
below. Note that the sizes [MB] are defined for B-mode and the storage time is defined for
M-mode, D-mode and Graph. In addition, for B(f)-mode, the number of storable frames is
calculated from the number of lines and the number of pixels per line.

Moreover, the cine memory has the following features.
‹
It is possible to read out the data from cine memory for line data storage.
‹
It is possible to write the data into cine memory for data review function.
‹
Since the memory access is performed on the main memory, it is possible in
high-speed reading and writing the data.
z Scan convert part (SC Process), Post Process part and Overlay Process part
In F37, the scan convert process, the post process and the overlay process are executed by
software with using dedicated graphics coprocessor called GPU (Graphics Processing Units).
To use the GPU, use a software API for multimedia processing called the DirectX.
These processes obtain the line data or the graph information from the Cine memory,
execute interpolation calculation corresponding to the individual display modes
(two-dimensional interpolation calculation for the plane mode; interpolation calculation also
performed for the line mode (M/D), graphs, etc.), and then output the data to the memory
space. The maximum number of outputted screens is four. Because the scan convert process
is executed based on the TV display frequency (60 Hz), it is executed asynchronously with
the ultrasound frame rate (using a different frequency). The display rate is controlled by
software so as to eliminate unnatural twitching and jittering on the screens. For low frame
rates such as a color flow, the frame accelerator is available as well.
For the data of the individual display modes generated by the scan convert function, the
display priority of ultrasound image is determined (e.g., the color image over the B/W
image). Then the data is converted with using palette table for RGB, and performed color

coding process before being sent.
The overlay process overlay the user interface information (characters and graphics) on the
ultrasound image data.
z Audio Process part
The Doppler sound is reproduced by playing the sound data sent from the DPM board with
DirectX. The R wave beep sound is obtained by playing the WAVE sound concurrently with
the R wave display.
z Video Interface part
Receives the LVDS video signal from CPU module via LVDS receiver IC. This signal is
converted to a DVI signal by the DVI transmitter IC and then outputted to the DVI
connector.
At the time of machine startup and shutdown, the video interface independently generates
synchronous signals and respectively outputs the startup screen and the shutdown screen.
For the analog video output, the video interface executes clipping process, resolution
conversion, progressive-interlace conversion and color space conversion to the images
received from the CPU module. The converted image data is converted to the component
video signals and the composite video signals by the video encoder IC, which are then
outputted respectively to the “Y/C OUT” connector and the “VIDEO OUT” connector.
For the analog video input, the video interface receives the component video signals from
the ”Y/C IN” connector via the video encoder IC. The video interface executes color space
conversion, interlace-progressive conversion, and resolution conversion to the received
image data, and finally overlaid it on the images from the CPU module.

Introduction
The Troubleshooting, being part of the Service Manual, is designed to give an indication for repairs.
The information in this section assumes that service is to be carried out by replacing a PCB or unit.
5-2
Precautions
When servicing according to the information in this section, pay extra attention to the following to
prevent another failure from occurring.
1) Be sure to turn off the power to the equipment whenever your remove PCBs, probes, cables, or the
like in the electrical system.
Be sure to unplug the power cable from the equipment or turn off the circuit breaker and then, wait
until the power LED on the operation panel turn off, when you remove a component to which
power is supplied when it is in the stand-by condition, such as PC boards and the operation panel.
2) To disassemble the equipment and begin the work, be sure to follow the disassembly procedure.
Incorrect disassembly of the equipment may damage it.
3) Before checking voltages and signal waveforms, you should become familiar with the
specifications and handling procedure of measuring instruments.
4) When grounding a test probe of a measuring instrument or any other instrument, you need to know
the locations where measured signal grounds are. Be sure to identify the type of ground (analog,
digital, AC, DC, high voltage, or low voltage) before using it.
z CAUTION z If a ground of test probe is not connected to the correct ground, it may not
be possible to observer the correct voltage value or waveform, or the
relevant measuring instrument and/or the ultrasound diagnostic equipment
may burn out.
5) Be sure to turn off the power to the ultrasound diagnostic equipment before connecting a test probe
of any measuring instrument to a measuring test point.
z CAUTION z In particular, when measuring high voltages, a circuit in the ultrasound
diagnostic equipment may be damaged. In addition, operator safety may
be compromised.
6) Before replacing or repairing a PCB, determine the compatibility or other information of PCBs
following the “Software/Hardware History”.
z CAUTION z Inserting an incompatible PCB into the equipment may cause it to burn
out.
7) Avoid changing the setting of a variable resistor or switch on a PCB unless you are sure the
relevant component is faulty.
See “VOLUME 1: Chapter 6, Performance Check” to determine whether the relevant component
is faulty.
See “VOLUME 2: Chapter 4, Adjustment” if readjustment are required.
z CAUTION z Changing a variable resistor or switch without any reason may produce a
new problem, making it impossible to repair.

Default Setting and Statuses
The PCB has switches and jumper connectors (JPs) that accommodate the default settings and
different specifications of the equipment. The equipment may malfunction and also cause a new
problem unless they are in specified states. Do not tamper with or make changes to switches and
jumper connectors other than the maintenance switches unless otherwise specified.
Some of the PCBs have LEDs that allow you to check the operation status of the relevant PCB and to
infer the state of failure. Some of the LEDs alone indicate the operation status of a circuit, whereas
others indicate the operation status in relation to other board. Thus, the failure is not necessarily
attributed to the board on which the relevant LED is installed. This section shows the layout of LEDs
and operation statuses.

Caution for Monitor repairing
5-7-1
When you have a failure on LCD monitor, it should be replaced by LCD monitor module or
whole LCD monitor, and DO NOT replace with the internal PC board or any parts on LCD
monitor.
If you disassemble the LCD monitor in the filed, we could not accept for monitor repairing
regardless in the warranty or not.
In addition, please be careful about the handling of LCD panel because there is the following
characteristic on it.
9 The LCD (Liquid Crystal Display) monitor has been manufactured with extremely high
precision, but there are some cases where screen pixels are black or constantly lit in one
color. Note that this is due to the characteristics of the LCD monitors, and is not a defect.
Please refer to description on the next section about the how to judge it.
9 When LCD monitor displays the images for a long time, an afterimage comes out and may
let you shorten life of the liquid crystal panel. Please use screensaver and so on to avoid
these.
9 Prevent an LCD screen from being injured by a hard thing or a sharp thing (a needle, pin).
9 When the LCD monitor gets too strong vibration and/or shock, it causes some damage and
the trouble of the screen part. Please carefully handle with it during the installation,
disassembling and transportation of LCD monitor.
9 DO NOT block up the vent part, avoid the installation on the side of heat generator, and
please install it in the good place of the ventilation as much as possible.
9 Do not use the LCD monitor in locations exposed to direct sunlight or well-light because
temperature inside of monitor will be increased or it will be difficult to see the image on the
monitor.
How to judge the dot defect of LCD monitor
5-7-2
Our Q.A. established the standard for a judgment of LCD dot defect. It judges the LCD is
faulty when there are 9 or more abnormal dots in a screen, on the other hand, it is
recognized as “Alright” when the abnormal dots are 8 or less.
z
Definitions
Dot Defect: A defect occurs in a pixel that one of the R, G, B color sell get abnormal
display.
1 picture element
(1 pixel)
Each R, G, B sell
is called “dot”.
Bright dot:
A defect that the dot is always displayed in brighter color (White, red,
green, blue, purple, light blue, yellow) on the LCD screen when it displays
“black” or dark color.
You can check it during the start-up of the machine (When the LCD is
black) or in the PRESET screen (Dark background).
5 - 18
MN2-2064 Rev.0
Chapter 5 Troubleshooting
Dark dot:
z
A defect that the dot always displayed in darker color (Red, green, blue,
purple, light blue and yellow) or it doesn’t light at all on the LCD screen
when it display “White” or brighter color. You can check it with “EXT”
screen or a test pattern display (If available).
Procedure and the environmental conditions
All LCD monitors are inspected with the procedure and the environmental conditions below.
You should follow this procedure and the conditions when you check the dot defect because
you would make a misjudgment if you did it outside the range of these conditions.
Distance:
View the screen visually at about 30 to 40 cm from the surface
of LCD monitor.
Viewing angle:
View the screen from the front perpendicularly against the
surface of LCD monitor (Vertically within +/- 10 degrees and
horizontally within +/- 10 degrees).
Surrounding light: Light the room with a fluorescent light (Day light type) at 300
to 500 lux (It is regular luminance of office room, factory etc.).
Room temperature: 20 to 25 degree Celsius (68 to 77 degree Fahrenheit)
zIMPORTANTz
There is tighter standard applied at the production of LCD
module, especially for “bright dot” is strictly checked at the
factory.
zIMPORTANTz
This standard is applied independently of the resolution
(Number of pixels) of the LCD monitor.

System start-up failure
If the system does not start or locks up during startup, refer to this section, and then perform repair
work.
5-8-1
Checking the power voltage
First of all, check the output voltage of the power supply board with referring section 5-6. If the
power lamp of the operation panel does not light up, refer to the “Operation checks on the
Power Supply board EP563600** by itself” in this chapter, and then check for the failure on the
power supply board itself.
Note that if the power cable of the machine is connected and the breaker on the rear side of the
machine is “ON”, +5V standby voltage (+5Vstb) is constantly supplied to the machine, and the
J802/J803 (Un Switched) of the AC outlet outputs AC power. If +5Vstb is being supplied
normally, the power switch on the operation panel lights up with orange color, which is referred
to as the standby condition.
5-8-2
Operation step after turn on the machine
When the power switch is pressed in the standby condition, the machine starts, following the
start-up sequence listed on the next and following pages. Displayed information at the LCD
monitor depends on the setting of the maintenance Dip SW. For details about the maintenance
Dip SW, see Section 5-5-7.
If the machine does not start-up, first check at which step in the start-up process the machine
stops. Next, troubleshoot corresponding to the step at which the machine stopped.

‹ Start-up failure and troubleshooting
(1) The monitor display is black from the time power is switched on. (Stops at Step 3 of the
start-up process.)
z
Check the seven-segment display (LED 15/LED 16) on EP560800**(EU-9142*).
Æ If it stops at “AC”, the BIOS did not recognize the DPM board EP562100**. Try to
replace the EU-9142*.
Æ If it stops at “00”, the COM Express Module did not start. Try to replace the
EU-9142*.
z
Check LED 13/LED 14 on EP560800**(EU-9142*).
Æ If LED13 is off and LED14 is on, the FPGA of IBP board EP560800** was not
configured. (Did not start even after 15 minutes or more.) Try to replace the
EU-9142*.
Æ If both LED13 and LED14 are off, the reset of the CPU has not been released. If
the machine does not start while the power voltage (+12V and +5Vstb) is being
output normally, Try to replace the EU-9142*.
z
Change maintenance SW2 to maintenance mode (MAINTE), and then check the
monitor display.
Æ If the machine stops at the F37 logo, as
shown in the image to the right, and any of
the following LED are off, it is possible that
the transfer of firmware to the front-end part
failed. It is highly likely that there is a
communication error between the front-end
and back-end. To resolve the issue, try to
replace the EU-9142*. If this issue occurs
immediately after upgrading, replacing the
hard disk drive, or restarting the machine
using CTRL+R and so on, turn the power off and on. If these LEDs turn on, the
problem has been resolved.

- EP5574: D217
- EP5575: D27, D28, D29
- EP5662: D10 (when option EU-9151 is installed)
z
Check the connection of the monitor cables.
Æ If no power is being supplied to the monitor, check the monitor power cable
connection, or try to replace the operation panel PNL-F37*.
Æ If no video signal is being supplied to the monitor, check the monitor signal
cable connection. In particular, check that connection to J350 on the
Backplane is correct. (Confirm that the cable was NOT connected to J351.)
z
Check the operation of the monitor unit.
Æ If the OSD functions of the monitor does not work, try to replace LCD monitor
IPF-1507*.
Æ If video signal from other devices or a general-purpose computer are not
displayed correctly on the monitor, try to replace LCD monitor IPF-1507*.

Network error
If there is a network error (DICOM communication error), see the following, and then perform repair
work.
1.
Check for hardware and software failures
Follow the procedure in the section 5-11-1, and check that the network function on the Backend
unit and network function on the operating system are working normally. If an error is found,
replace the Backend unit or hard disk drive.
2.
Checking the network environment
Run a ping test for the network connection destination (DICOM image server, hub/router,
peripheral computers, and so on), and check communication.
If there is no communication, see the section 5-11-2, and check that there are no errors in the
network settings of the ultrasound diagnostic machine itself. Next, check for problems in the
settings of the connection destination network device.
{ Reference { For the ping test, use the network protocol named ICMP. Depending on the
computer settings, it is possible to set no response to echo requests in the ICMP
protocol.
If there are no problems with the DICOM function, and the ping test is
unsuccessful, there are no particular problems for usage.
If there are no problems with any of the settings, check with the network administrator of the
facility for unplugged network cables (LAN cables) and problems with hubs, routers, and
connection destination network devices.
If infrequent network problems are occurring, see 5-11-5, and then acquire and check the
communication data (packets) on the network. Consult with our technical support regarding
analysis of acquired data, and so on.
3.
Checking the DICOM environment
Run a C-Echo test on the network connection destination DICOM device, and check
communication.
If there is no communication, see 5-11-2, and check that there are no errors in the DICOM
settings of the ultrasound machine itself. Next, check for problems in the settings of the
connection destination DICOM device.
{ Reference { For the C-Echo test, a service called Verification for DICOM communication
is used. Depending on the connection destination DICOM device, this service
may not be supported, and may not respond to C-Echo.
If there are no problems with the DICOM function, and the C-Echo test is
unsuccessful, there are no particular problems for usage.
4.
Interpretation mismatch in DICOM communication
DICOM communication may fail because of interpretation differences for the DICOM
specifications of communication destination DICOM devices. In such cases, see 5-11-3 through
5-11-4, and then perform troubleshooting.

Check for hardware and software malfunctions
5-11-1
Check that the Backend unit network function and operating system network function are
operating normally.
1.
Checking the Backend unit
See 5-12-1, and then use the CPU self-diagnostic tool to diagnose the hardware. If this
function does not find any errors in the “PCI Network”, the network function installed in the
Backend unit is operating normally.
2.
Checking the network function on the OS
Check that the computer and ultrasound machine are connected by a network cable (cross
cable) using a peer to peer connection, and then check that the network function is operating
normally.
While any network settings for the ultrasound machine and computer are acceptable, the
following is a basic connection example.
(1)
Configure the ultrasound machine and computer network settings as follows.
IP address
Subnet mask

Use a network cable (cross cable) to directly connect the ultrasound machine and
computer.
Cross cable
IP: 10.20.30.2
IP: 10.20.30.1
(3)
Perform a ping test from the ultrasound machine to the computer (or vice versa). If a
response is received without issue, the operating system network function is operating
normally.
{ Reference { Depending on the computer network settings, it is possible to obtain no
response to echo requests for ping command.
If the ping test fails from the ultrasound machine but succeeds from the
computer, there are no problems.

N-ACTION, a commitment request sent from the machine to the server,
and N-EVENT-REPORT, a commitment result sent back to the
machine from the server.
If a commitment request is sent successfully, the machine waits for the
result from the server. However, the result may not be sent back
because of server trouble or another reason. In consideration of such
cases, a commitment request is regarded as rejected after a certain
amount of time, and the request must be sent again. This amount of time
is configured using the Transaction Limit setting.

Troubleshooting image storage operations
To resolve DICOM communication problems, it is necessary to acquire DICOM communication
logs from the maintenance menu, and then determine the cause of the problem from the logs.
This section describes how to handle problems from various causes.
For the method to acquire DICOM logs, see “Volume 2: Chapter 3, Service information”. When
it is necessary to analyze the logs, add the machine information to the acquired logs, and then
contact our technical support.
5-11-3-1 Association abort due to transfer syntax mismatches
During association for typical DICOM communication, the server (SCP: Service Class
Provider) selects the transfer syntax it can receive from the transfer syntax list provided by the
machine (SCU: Service Class User), and then data sending starts using this transfer syntax.
However, some servers cannot receive data even when the machine sends data using the transfer
syntax specified by the server. In addition, data transfer using a particular transfer syntax may be
required.
In such cases, it is possible to apply limitations to the transfer syntax proposed by the machine.
See the following section, and then change the settings.
1. Go to the Review window.
To access the maintenance switch, remove the right side cover and main chassis connection
cover.
2. Set maintenance Dip SW1 to “↓ ON” and Dip SW2 to “↓ MAINTE”.

contamination is hard to remove, moisturize the cotton swab with a tiny amount of
neutral detergent, and clean it off.
e) Return the ball to the original position and install the ring
6) Equipment circumference and power plug
Remove dust and moisture. If the equipment is used in dusty conditions, it may be badly
ventilated and the inside the equipment may become extremely hot. A high level of moisture
may cause failure of the equipment or leakage of electricity.
If you leave the power cord plugged in an outlet for a long period of time, dust may
accumulate gradually in the space between the power plug and the receptacle. The dust may
then become damp, causing a spark discharge between electrodes of the plug (called
“Tracking phenomenon”). Particularly if the power plug is not correctly inserted into the
receptacle, there will be a higher possibility that a tracking phenomenon will occur due to the
synergistic effect of defective contact and heat. To prevent this, remove the plug from the
receptacle once in a while and thoroughly wipe off any dust using a dry cloth before plugging
it in again.

Safety check
To conduct this safety check, refer to the Electrical Safety Manual (MN2-0205). This section is a
supplementary explanation dedicated to ultrasound diagnostic instrument F37.
zIMPORTANTz The safety check is intended to determine the electrical safety
performance of the equipment. The procedures and standard
values for the safety check vary depending on the classification
for the degree of protection against surges.
Ultrasound diagnostic instrument F37 falls into "Type BF applied
part" as the classification for the degree of protection against
surge.
The safety check should be conducted based on IEC 60601-1 - General requirements for Safety.
1) Checking continuity of protective earth cable
For Ultrasound diagnostic instrument F37, measure the continuity between the protective
earth terminal of the power plug and the following part.
Power cable for
200V~240V
Screw on the panel base cover
電源ケーブル
Power
cable for
100V~120V
2) Checking the insulation resistance
No supplementary items are available.
3) Leakage current
zIMPORTANTz Because Ultrasound diagnostic instrument F37 has a built-in
hard disk, when you use HIOKI 3155 or other leakage current
meter with an automatic measurement function, do not use the
function that automatically switches power polarities. Instead
of that, turn off the power of each device one by one after it is
booted up completely, change measurement conditions of the
leakage current meter, and then measure the leakage current.
z
Earth leakage current
Measure the earth leakage current in STAND BY mode.
z
Enclosure leakage current
6 - 19
MN2-2064 Rev.0
Chapter 6 Performance Check
Measure leakage current (a) flowing from the equipment cover to the earth, and leakage
current (b) flowing between covers of the equipment.
¾ Enclosure Leakage Current (a)
Measure the leakage current flowing from the keyboard part on the operation panel
to the earth.
¾ Enclosure Leakage Current (b)
Measure the leakage current flowing from the keyboard part on the operation panel
to the top cover (If the printer is installed, use top of fixture plate instead).
z
Patient leakage current I
Measure the leakage current flowing from the part contact with the patient (applied part)
to the earth.
z
Patient leakage current III
Measure the leakage current flowing from the equipment to the earth when voltage
[Rated voltage + 10% of rated voltage] is applied to the probe.
z
Patient auxiliary current (To be measured only when PEU-F37 is connected)
Measure between the ECG black lead and other ECG leads that bound read and green
together.
