CVS-FX2/FX2BB Introduction
0093102004-03 ix
Introduction
CVS-FX2 is the 15inch LCD color echo sounder that can display images in 4 optional
frequencies.
CVS-FX2BB is the Black Box type without the display unit of CVS-FX2, for which customer
can select the display monitor of preference. The external monitor and connecting cable are
user supply.
This unit equipped with the latest digital process can accurately display circumstances in the
water under all conditions.
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. (Only CVS-FX2 )
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.
(Only CVS-FX2 )
This unit has high waterproof level and can be installed in an open bridge. (Only
CVS-FX2 )
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)
The display and the operation units can be easility installed from the front side by flush
mounting. (Flush mounting of monitor is only for CVS-FX2).
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).
The data for image, waypoint, and setting can be backed up in the USB memory and the
SD card, to be recalled later.
As the operation unit is separated, operation away from the processor and the display units
is possible.

1.1 Change of TX Power
The strength of TX Power (transmission
output) can be changed.
When water depth is 50 m or less, the gain
of images are sometimes too high. In such
cases, the gain can be set appropriately by
reducing the [TX Power]. When own
equipment is affecting the echo sounders of
other boats, the interference noise to the
other boats can be reduced by weakening
the TX Power.

1.3 Making of reflection strength at
shallow and deep depth equal
At [Optimized] of TVG Type, it is set as the
bottom signal can be seen at a constant
level. At [Manual], the reflection strength of
fish depending on the depth can be set to be
seen uniformly.
1.3.1 Changing of TVG Type
TVG*2- TVG Type
TVG is a function to display images, by
correcting the attenuation of ultrasonic
sound through propagation in water and by
making reflection strength from deeper and
shallower depth equal,

2. Select [TVG] - [TVG Type]
3. Press [ ]of .
The setup box of [TVG Type] will be
displayed.
4. Press [▲] and [▼] to select a type.
At [Optimized], bottom signal will be
corrected to be a constant level at all
ranges. At the [TVG Adjust], it is possible
to change the effect of correction on
signal shallower than the start point.
At [Manual], user is to set [TVG Strength],
[TVG Depth] and [TVG Adjust] to produce
desired performance. (See the Basic
Operation Manual, “2.2.6 Adjustment of
TVG”).
5. Press to close the menu.
Main changing items here are as
follows:
To change TVG Type
To change TVG Strength
To change TVG Depth
*1 Dynamic Range: This is the function to expand and narrow down the signal range from blue to red in
images.
*2 TVG (Time variable gain): The signal strength is different between deep and shallow water and this is the
function to correct this.
