9. OPERATION OF THE MACHINE
9.1. OPERATION PRACTICES
A. Wear a lead apron while you make exposures.
B. Stay distance at least 2 m from the unit or extend the cord of hand switch as long as possible in
order to secure enough space for your safety.
C. Use proper field size and technical values for each procedure to minimize x-ray exposure dose
and gain the best radiographic result.
D. Be careful about the decimal point on the mAs display in order to acquire intended mAs values.
E. When you make exposure to the patient on the bed, ask visitors to leave the room first and
keep appropriate distance from the patient.
F. Pay attention to the maintenance schedule of the device and keep up with it.
G. Cumulative radiation dose usually does not exceed recommended maximum levels. However, if
you make radiographic exposures using high kV and mAs quite often, the evaluation of the
specialist is needed to check whether extra protective devices are necessary for the user or not.
WARNING
Please check weather the voltage and frequency of the power supply are in
accordance with the figures written in the system labels, which attached on the
body of the machine. The levels of voltage should move within ±10% of the
nominal values.
CAUTION
The operation of the machine should not be started unless all verifications and
connections are fully prepared.
9.2. POSITIONING OF PATIENT
A. Place the loaded cassette on the patient’s backside.
B. Arrange the SID (Focal Spot to Image Receptor Distance) using a scale located on the side of
the collimator.
C. Turn on the collimator lamp and laser pointer by pushing collimator/laser on switch.
D. Adjust the size of the x-ray beam in accordance with the film size using the x-ray field
adjustment knobs. Turn off the collimator and laser pointer after 30 seconds on the timer.
CAUTION
For the first installation of the machine or operation after long period of non-use, it
needs to be preheated to secure long service life of the tube. Following method of
pilot test will relieve the damage on the x-ray tube. Operate the machine with low kV
values (50kV 5mAs) three times in row and execute with higher values [70kV 5mAs]
three times in row again. Then high kV values [90kV 5mAs] will be applied without
big troubles or pressures on the machine.

11. REMOTE CONTROL FUCTION & OPERATION
11.1. INTRODUCTION
Currently, mAs, kVp and Pre-set memory techniques (Prom memory) can be selected by the operator
by depressing push buttons or by scrolling displays on a control panel. Each technique or mode
selection depends on an anatomic region or view for radiographic examination. The collimator lamp
and laser pointer is turned “on” by the lamp push-button and turned “off” by a 30 second collimator
timer run off.
Many portable operators and field users have suggested we find a better way to select an exposure
technique and parameters along with mAs, kVp and pre-set Prom memory values. Most field operators
hold portable X-Ray units with one hand, while holding the exposure hand switch with the other hand.
This makes selecting technique factors on the control panel awkward without dropping the portable
unit or hand switch. We have modified our X-ray portable software and functions of the Prep. and
Exposure hand switch to allow selection of all exposure parameters (mAs & kVp) and control of the
collimator lamp and laser beam.
The exposure hand switch consists of a two step hand switch. The first (1) stage of the hand switch is
called the “Preparation (Prep. or Ready)” stage. The second (2) stage of the hand switch is called the
“Exposure (Exp or X-Ray out)“ stage. (See drawing 1.)
All functions of the remote control described above are executed by clicking the first stage on the hand
switch which is the “Prep.” mode of operation. Each remote control function and technique value
selection is described below.

11.2.
REMOTE CONTROL MODE
12
Product Manual: PXP-40HF
Ltd.
Poskom Co.,
The kVp and mAs setting, memory selection and collimator lamp and laser pointer illumination
functions are controlled remotely by the hand switch by pressing the “Prep.” stage push-button as
follows:
ATTENTION
Click the “Prep.” hand switch three (3) times consecutively. This will allow you
to enter in the “remote hand control” menu mode for operation.
<TRIPLE CLICK>
11.3. MEMORY SELELCTION
When you click the PREP stage hand switch quickly three (3) times, the Pre-set Memory station LED
(PXP-20HF: 1-4 / PXP-40HF & 60HF: 1-8) will blink sequentially as well as the kVp and mAs LED
readouts. Make a single (1) click with the hand switch when the desired pre-set memory station lamp
begins to blink. This will cause the pre-set memory data to be selected and displayed in the control
LCD window.
NOTE
All pre-set memory data should be entered and stored at each memory station (PXP-20HF: 1-4 /
PXP-60HF: 1-8), prior to performing the above mode of operation.
11.4.
kVp SELELCTION
One (1) click of the “Prep” switch will cause the kVp LED readout to blink. You will now be in the kVp
selection menu mode. The kVp values increase by one (1) kVp unit per click of the “Prep.” switch. If
you depress and hold the prep switch for a few second, the kVp readout will increases rapidly up to
the maximum value (PXP-20HF: 90kVp / PXP-40HF & 60HF: 100kVp). The kVp readout will circulate
from lowest to highest values as long as you hold and press the button. When the desired kV readout
appears on the control display panel, release the prep hand switch and wait for a few seconds. The
kVp value will set up automatically.
13
Product Manual: PXP-40HF
Ltd.
11.5.
Poskom Co.,
mAs SELECTION
mAs selection is similar to the kVp selection mode. Click the “Prep” hand switch once to make the
mAs LED readout blink. You will be in the mAs selection menu mode. The mAs value will increase with
each click of the “Prep” switch (0.4mAs to the maximum mAs of each portable x-ray unit). If you wish
to increase the mAs value quickly, simply hold the “Prep” switch down one stage. (PX-20HF: 50mAs /
PXP-40HF & 60HF: 100mAs). The mAs readout will circulate as long as you hold the “Prep” switch.
When the desired mAs readout appears on the control display panel, release the prep hand switch
and wait for a few seconds. Then mAs value will set automatically.
11.6.
COLLIMATOR / LASER BEAM TURNED ON
ATTENTION
Click the Prep. hand switch rapidly twice. The collimator lamp and laser
pointer beam will illuminate for X-ray exposure positioning.
<DOUBLE CLICK>
With the exposure technique (mAs & kVp) set with your remote hand switch, you are ready to make a
radiographic exposure for examination. It is very important to position the right region of interest on a
patient’s anatomy. Therefore, the collimator beam must be turned on to confirm the size of region and
size of film covered. The laser beam must also be turned on for checking the precise center of the
target prior to making a final X-ray exposure. When the Prep switch is rapidly clicked twice, the
collimator lamp and laser beam will turn on simultaneously until the lamp timer (30 seconds) runs off.
However, it will turn off automatically when x-ray exposure sequence is completed.
11.7.
X-RAY EXPOSURE
WARNING
When an X-ray exposure is made in a room or outdoors, lower radiation will scatter throughout the
surrounding area. An authorized operator is expected to take precautions and is highly recommended
to ware a lead apron and gloves if necessary for your patient’s and your own protection.
After the x-ray exposure technique is selected and collimator light beam size is adjusted with the
collimator blade knob, an x-ray exposure can be made by an authorized individual of the medical clinic
or hospital.
X-RAY EXPOSURE SEQUENCE:
A. Press the Prep hand switch (1st stage) and hold
B. Press down the 2nd stage hand switch. Exposure will be
made automatically by the exposure timer.
