Introduction
Introduction
CVS-FX1 is an LCD color echo sounder that can display images in 4 optional frequencies.
This unit equipped with the latest digital process can accurately display circumstances in the
water under all conditions, with a good match with the high brilliance 12.1 inch LCD.
The main features of this unit are as follows:
This unit is a multi-frequency echo sounder with broadband transducers.
With a simple operation on a menu, frequencies up to 4 can be optionally set within a wide
range.
With digital reception processing, the high resolution in shallow depth and the noise
reduction capability in deep depth are both attainable. In addition, optimum images can be
displayed by the auto mode function.
The high-performance LCD maintains high visibility under any conditions.
With adoption of a special filter (AR coated), images can be seen clearly even under the
direct sunlight. Well protected against reflection on the LCD screen and dew condensation.
This unit has high waterproof level and can be installed in an open bridge.
Sona-ToneTM (Sonar sound) function provides fish school status by sound..
Up to 500 graphic images can be stored. Homing function is available by pushing event
key while recalling the stored images, to provide navigation guidance to the designated
position (optional GPS is required).
Various alarm functions are available (Bottom, school of fish, water temperature*, vessel
speed*, arrival*, XTE*, power source).
(Note: The mark * denotes that the connection of optional sensors is required)
By flush mounting, the unit can be easily installed from the front side.
RGB analog output to an external monitor is provided as standard. The use of external
monitor enables to observe the echo sounder images from the place distant from the main
unit (External monitor is owner supply).

Chapter 2 Basic operation
Setting up of frequency:
1. Relation between a transceiver and display screen
For CVS-FX1, there are two types of transceiver for high frequency and low frequency,
and each transceiver has two channels of channel 1 and channel 2.
High frequency 1 is the channel 1 for high frequency.
High frequency 2 is the channel 2 for high frequency.
Low frequency 1 is the channel 1 for low frequency.
Low frequency 2 is the channel 2 for low frequency.
2.
Limitation in setting of high and low frequencies:
In the case of a broadband transducer, the cable at high frequency side of the transducer
shall be connected to the high frequency terminal and the cable at low frequency side of
transducer shall be connected to low frequency terminal.
The frequency range to be set has the following limitations per transducer.
Name of transducer
TDM-052
TDM-062
Frequency range
of low frequency
38 to 75 kHz
38 to 75 kHz
Frequency range
of high frequency
130 to 210 kHz
85 to 135 kHz
Caution: If the frequency setting exceeds the ranges above, gain will not be enough
to let the transducer perform to the designated specification.
When the other transducer than broadband type is connected, please connect the cable
for low frequency of the transducer to the low frequency terminal and the cable for high
frequency of the transducer to the high frequency terminal, and set the designated
frequency of the transducer.
3.
4.
5.
Simultaneous transmission and reception*1 and alternate transmission and reception*2
Two transceivers for high frequency and low frequency transmit and receive
simultaneously, and the channel 1 and channel 2 of each transceiver operate in alternate
transmission and reception.
When the same frequency is set for high frequencies 1 and 2 or low frequencies 1 and 2,
alternate transmission and reception do not operate. Transmission and reception are
performed by only channel 1 and the image is displayed using the channel 1 data by the
channel 2 gain setting.
The conditions when alternate transmission and reception can operate even when the
same frequency is set for channels 1 and 2:
If pulse width is different
If frequency bandwidth is different
If range is different.
If shift is different.
If the types of display zoom is different.
*1 Simultaneous transmission and reception: Each transmitter and receiver for high frequency and low frequency
operates simultaneously.
*2 Alternate transmission and reception: Channels 1 and 2 of high frequency and channels 1 and 2 of low frequency
transmit and receive alternately by each channel. The image scroll speed will drop
to a half of that of simultaneous transmission and reception

2.1.4 Display of mixed images
Mixed images are combination of high and low frequency images by signal processing. The
main purpose is to identify small fish, such as whitebait, from other fish school. There are 5
types for mixing methods and they are switchable in application.
Types of mixed images:
1. Mix type A
Images in high frequency and low frequency are compared. The red level signal indicates
high frequency images. For the signal at lower level than that, the high frequency signal is
displayed in gray color.
As fish schools with strong high frequency signal are highlighted, this is helpful for
identification of fish schools near own boat’s position.
2. Mix type B
Only when high frequency signal is stronger than low frequency signal, the low frequency
signal is subtracted from the high frequency signal, and the difference is displayed with
color gradation.
The images existing only in high frequency are highlighted.
Small fish such as whitebait can be displayed in high frequency, but not in low frequency.
This is helpful, therefore, for identification of schools of small fish.
3. Mix type C
Images in high frequency and low frequency are compared. The red level signal indicates
high frequency images. For the signal at lower level than that, only when the high
frequency signal is stronger than the low frequency signal, the low frequency is subtracted
from the high frequency and the difference is displayed with color gradation.
Strong signal with high frequency and images only in high frequency are highlighted.
This is helpful, therefore, for identification of fish school near own boat and school of small
fish such as whitebait.
4. Mix type D
Signals of images of high and low frequencies are compared, and the stronger signal is
displayed with color gradation.
This is completely combined image of high and low frequencies. Without viewing of each of
high and low frequencies images, only this one image can tell the conditions in water.
5. Fish size in fish school size
Comparing signals of high and low frequencies, only signal with higher level of high
frequency is displayed as difference in the order of strength, from red (strongest) to
greenish yellow with color gradation. Low frequency images are indicated in greenish
yellow to light blue with color gradation and the mixed image of them is displayed.
For example, when high frequency is 200 kHz, the wavelength of underwater acoustic
wave is 0.75 cm, and when low frequency is 50 kHz, the wavelength of underwater
acoustic wave is 3.0 cm. In the image of low frequency 50 kHz, fish smaller than 3 cm is
hardly detected.
As school of small fish such as whitebait is clearly displayed in high frequency signal with
short wavelength, only school of small size fish is displayed in warm color from red to
greenish yellow in fish school mode.
By this, it is easy to identify smaller size than 3.0 cm.

2.1.5 Selection of pulse length
Pulse length can be switched to 4 steps: of Short, Medium, Long and Fixed.
This change of pulse length causes changes in resolution of images from the echo sounder
and the signal to be displayed changes. Shorter pulse length increases resolution, but its
power decreases. Other way around, longer width decreases resolution but increases power.
By this nature, the pulse length is switched depending on the range: to Short (narrow) at
shallow range and to Long (wide) at deep range, except for the case of setting at [Fixed].
When pulse length is switched:
1. For the setup up of pulse length, based on the setup at [Medium] as reference, at [short],
the pulse length is switched to the same pulse length as [Medium] pulse length with 1/2 of
the range used, and at [Long], to the same pulse length as [Medium] pulse length with 1.5
times of the range used.
When signals in images of fish are not visible at the range used, setup at [Short] increases
small response, and setup at [Long] highlights larger response while decreasing small
responses.
2. When pulse length is set at [Fixed], the width is constant regardless of switching of range.
Please set at [Fixed], to avoid change of response from fish by switching of range.
To select pulse length:
1. Press [CM] key (lights red) used.
When CM1 is lit red, press [CM1] key
.
2. CM menu is displayed.
3. Moving the cursor with

2.1.6 Selection of frequency bandwidth
Frequency bandwidth can be switched to 4 steps: Narrow, Medium, Wide and Fixed. The
change of frequency bandwidth results in change of the resolution of echo sounder and
change of signals in the displayed images. If the frequency bandwidth is wide, the resolution
becomes high. Other way around, if it is narrow, resolution becomes low.
By this nature, the frequency bandwidth is switched depending on the range: to wide at
shallow range and to narrow at deep range, except for the case of setting at [Fixed].
When frequency bandwidth is switched:
1. For the setup up of frequency bandwidth, based on the setup at [Wide] as reference, at
[Medium], the bandwidth is switched over to the same bandwidth of [Wide] bandwidth that
is 1.5 times of the range used, and at [Narrow], to the minimum bandwidth.
When size of target fish matches the frequency wavelength in use, setup up at [Medium] or
[Narrow] highlights the images and increase visibility. When pulse length is set at [Short]
and frequency bandwidth at [Narrow], response smaller than wavelength is reduced and
noise reduction effect is expected.
2. When frequency bandwidth is setup at [Fixed], the bandwidth is constant regardless of
switching of range.
To select frequency bandwidth:
1. Press [CM] key (lights red) used.
When CM1 is lit red, press [CM1] key

2.2.5 Adjustment of image gain
On CVS-FX1,gain of 4-frequency images can be adjusted individually.
For gain adjustment, there are two modes: individual mode and synchronized mode. In the
individual mode, the gain is adjusted individually on a selected operation screen. In
synchronized mode, the gain on all screens are adjusted all together by one gain adjustment
knob after gain adjustment is optimized individually for each screens.
In the synchronized gain, the gain of all screens change keeping the gain difference between
screens.
On CVS-FX1, the gain of all screens including images in the past changes by operation of the
gain knobs. Also, it can be switched to a mode in which only the gain of the current image
changes, to watch changes by the gain operation.
If the gain is increased too much, there is too much noise to make distinctions with signs of
fish.
If the gain is decreased too much, images and fish signs become too faint to distinguish.
Adjust the gain to your preference while watching the image.
<Example of gain adjusted images>

To use of optimized TVG:
Optimized TVG corrects the reflected signal from shallower than the [Depth] where color is
produced with maximum level. This is done by having room for gain adjustment, in
reference to the diffusional attenuation and absorption attenuation of ultrasonic sound.
By optimized TVG, unnecessary reflection such as noise is eliminated, and necessary
reflection from single fish and fish schools is clearly displayed at the same sensitivity
regardless of their depth.
As optimized TVG always corrects optimized TVG, no adjustment is basically needed. Only
fitting to a desired gain with a gain knob is required.
However, when it is felt that the gain is short due to the excess correction of TVG for
shallower range, please adjust to a desired gain by changing the [Adjust].

Chapter 2 Basic operation
To manually correct TVG:
The reflected signals of echo sounder have less sensitivity due to attenuation, as depth is
deeper.
In the TVG correction for CVS-FX1, a reference point of depth for correction is to be
determined. This reference point is [TVG Depth].
Reflected signals from a shallower depth than this reference point are corrected to have the
same sensitivity as that of the reference point.
In [Strength], the amount of change in this correction is set. The larger the value of [Strength]
becomes, the larger the amount of change becomes. (See the figure below)
For reflected signals from shallower positions, amount of correction becomes larger. When
[Strength] is set large, the correction amount for shallow depth may seem too much. In such
cases, if the [Adjust] is set at the depth at which correction seems too much, the correction
amount at shallower depth than the depth becomes the same as the correction amount at the
starting position, and can set off the over correction.
Setting should be performed in combination of the items above.
Adjustment of TVG strength of manual TVG:
[TVG Strength] decides the amount of change for TVG correction. The larger the value of
[TVG Strength] is, the bigger the amount of change is.

2.3 Changing of the image scroll speed
The image scroll speed can be changed at 14 steps of [Speed -2], [Speed -1], • • • [Stop],
[Speed 2], • • • [Speed 9]. The larger the speed number is, the slower the image scroll speed
becomes.
The image scroll speed of echo sounders is faster for shallow ranges and slower for deeper
ranges depending on the display ranges.
When the image speed at shallow ranges seems too fast, [Image Speed] is used to make the
speed slower.
When sea bottom is bedrock and has strong reflection strength, the multipath reflection
between seawater surfaces remains as reverb and may display false image*1. To eliminate
the false images, the image scroll speed may be slowed down to wait the next transmission
and reception until the reverb disappears.
The scroll of images can be stopped.
Speed 0 : The image scroll speed is 2 times faster by enlarging the original image 2 times.
Speed -2: The image scroll speed is 4 times faster by enlarging the original image 4 times.
To change image scroll speed:
1. Press [Image Speed] key

[Image Speed] adjustment box is displayed.

1. While [Image Speed] adjustment box is displayed, press [Image Speed] key
.
Move upward the cursor, and [Image Speed] is set to a faster speed.
*1False image: When sea bottom material is bedrock with high reflection ratio of ultrasonic sound, the reflected signals at
the sea bottom are reflected by the seawater surface and again by the sea bottom. This may be repeated
many times. This repeat of reflection remains as reverb. If the reverb remains at the next transmission and
reception, the image is a mixture with normal reflection and the reverb. This reverb is called as false
images.

2.4 Finding out depth of targets in images (VRM operation)
VRM (Variable Range Marker) is a mobile marker to measure the depth of targets such as fish
schools, and indicates lines and depth values of the lines.
This can be also used as an indication of depth for casting net, etc.
VRM can display the second VRM set at a certain interval under the first VRM. This second
VRM follows the movement of the first one with the interval. This can be used as a measure
for depth of casting net.
There are two modes: to display on only one screen of the 4 frequencies and to display across
the all 4 screens.
In the display on the whole screen mode, the same depth is indicated on all screens at
synchronized range/shift. Display and operation can be done on each screen at individual
range/shift.

2.5 Reduction of noise on images
Images of echo sounders display noise due to various causes.
The causes of noise are:
1. Interference caused by reception of signals transmitted by other echo sounders
2. Blur due to micro animate beings such as plankton
3. Noise caused by electric signal synchronized with transceiver
CVS-FX1 is equipped with functions to weaken the effect by each cause.
2.5.1 To reject interference
Interference is generated by the reception of signals transmitted by other echo sounders.
CVS-FX1 can eliminate interference by the following two methods:
1. To shift your own frequency from the frequency used by other echo sounders, to avoid
reception of interference wave.
2. To reject interference by setting [IR (Interference Rejection) ] function.

2.5.2 To erase the weak response from dust and plankton, etc.
To erase the weak response from dust and microbes such as plankton in seawater, there are
following 4 methods:
1. Setting TVG
2. Shortening pulse length and narrowing frequency bandwidth
3. Setting [Color Erase] function
4. Setting [IR] (Interference rejection) function
When TVG is effective:
In order to erase the response from dust and plankton at shallow depth of the displayed
screen, setting TVG is effective.
TVG can be set in two ways, [Optimized TVG] and [Manual TVG].
In the case of setting in [Optimized TVG], the images are clear with less interference noise
down to water depth of approximately 100 m.
As for the setting of [Optimized TVG], see “To use of optimized TVG”, p 2 - 57.
By setting [Manual TVG], noise reduction setting is possible to preference.
As for the setup of [Manual TVG], see “To adjust with manual TVG”, p 2 - 60.
When shortening pulse length and narrowing frequency bandwidth are effective:
When the range used is less than 100 m and the response from dust and plankton on whole
screen is to be erased, it would be effective to set the pulse length at [Short] and the
frequency bandwidth at [Narrow].
By this setting, fine images such as dust and plankton are erased.
It can be used for highlighting of images of aimed fish and erasing of response smaller than those.
As for the setup of [Pulse Length], see “2.1.5 Selection of pulse length”, p 2 - 19.
As for the setup of [Frequency Bandwidth], see “2.1.6 Selection of frequency bandwidth”,
p 2 - 22.
When [Color Erase] is effective:
When the response from dust and plankton displayed in light bluish color is to be erased, it is
effective to use [Color Erase] function.
The response of dust and plankton displayed in stronger color than green could not be erased.
The color of aimed fish images and appearance of expanding response are displayed as it is
and unnecessary response from dust and plankton is erased.

When [Noise Reduction] is effective:
When the response from dust and plankton is to be diminished regardless of water depth and
color, [Noise Reduction] is effective.
For [Noise Reduction] function, by narrowing the dynamic range and reducing tone graduation
of colors, the color of weak response level becomes less visible.

3.1 To use [CM] keys
[CM] (Condition Memory) key is used to memorize setting conditions of an echo sounder
and recall them with one touch of a key button. For example, it is possible to switch the
setting for seine fishing to the setting of squid fishing with one touch of a key button. CVS-FX1
is equipped with six [CM] keys, so can be used as if six units of echo sounders were used at a
time.
[CM] key has three major functionality:
Switching screen mode
Switching all settings with one touch of a button (setting values for each fishing
method can be memorized, recalled and switched with one touch of a button)
Usually it is used for switching screen modes, and when the type of fishing is
changed, a particular setting can be switched to the other setting with one touch of
a button, if specific values are memorized.
Please proceed to the corresponding pages for the functionality of your interest.
To use as a switching key of screen modes:
Types of screen (4-frequency, 2-frequency, Single-frequency, Zoom) are switched over
frequently.
Settings of menu, shift and gain, etc. are not decided.
Please proceed to “3.1.1 To use [CM] key for switching screen modes”, p 3-2.
To use as one touch switching key of all settings
Types of screen are rarely changed.
Settings of menu, range, shift and gain, etc. have been determined by fishing methods, and all
settings should be changed at once when fishing method is changed.
Please proceed to “3.1.2 To use [CM] keys as one touch switch to memorized setting to the
fishing positions”, p 3-6.
Usually the key is used for switching screen modes, and when fishing method is changed,
it is used as one touch switching key.
Types of screen (4-frequency, 2-frequency, Single-frequency, Zoom) are switched over
