Points to note in use of
fish symbol
The values displayed by this function may be
incorrect depending on various environmental
conditions. In use of these values, please
understand the following factors of error, and
use them as reference:
【Factors of error】
】
1
When there are overlapping responses,
all of them may be displayed to show the
magnitude of a point.
2
The strength of reflection may depend on
the output of transducer unit and may
result in a factor of error.
3
The strength of reflection may depend on
the kind of fish and may result in a factor
of error. As for the fish such as the squid
which don't have an air bladder, the error
is big.
4
Fish banks, fishing net, fishing equipment,
air bubbles and floating objects, etc. may
be detected and displayed.
5
When the transducer unit is mounted in
inner-hull, there may be cases where
response cannot be detected depending
on attenuation, and large error may be
generated.
6
The strength of reflection may depend on
the difference of ship handling such as
stoppage and cruising, and may result in
a factor of error.
7
Each transducer unit may have difference
in transmission/receiving performance to
cause error.

The various items in the menu are explained.
The TVG adjusts the difference of strength
between echoes reflected from the shallower
depth and echoes reflected from deeper depth
so that the reflection can be uniformed.

Press the [MENU] key to close the menu.
Gain (TD) L
The deeper the depth is, the reflected signal of
echo sounder becomes weaker due to
attenuation. Thus, comparing with the signal
reflected from the same size fish, the signal
reflected from the fish in the shallower depth is
stronger than that in the deeper depth. The
TVG adjusts the echo signal reflected from the
shallower depth to be equal to that reflected
from deeper depth by decreasing the receiver
gain so that the effect that the strength of echo
signal reflected from the shallower depth looks
the same as that reflected from the deeper
depth provided. The level of adjustment due to
the depth increases in the order of weak →
medium → strong. When set to "Strong", the
TVG provides strongest effect that reduces
various noises around oscillation line.

5.3 Installation of Transducer
The standard installation of this echo sounder is shown in figure 5.6.
Figure 5.6 Installation of Transducer
In case of Inner-hull
Using the optional inner-hull kit (MFB-04), install the transducer to the inner side of ship’s bottom.
Caution on installation
(1) Select the location where no bubble is
generated during navigation.
(2) Select the relatively thin location of ship’s
bottom.
(3) Be sure to remove oil on the contact
surface. File the contact surface with sand
paper (#400) so that the adhesive strength will
increase.
(4) The adhered surface will dry in about two
hours.
(5) Leave the unit for a whole day and fill in
the coolant. More than 80 % of the transducer
should be submerged in the coolant.
Figure 5.7 Inner-Hull installation
Caution: Confirm a place of the installation of inner-hull in the manufacturer of the ship
and so on. The inner-hull device is for more effective performance method. The gain
falls in comparison with the through-hull performance dramatically. Low frequency (50
kHz) may not be used due to large signal attenuation. Depth range performance using
200 kHz Transducer in case of inner-hull will also be less about 50% than that of
through-hull.
Caution: In the case of fishing boats, FRP contained air bubbles and foarmed materials
that would prevent ultrasound from penetration have been likely used. Therefore, even
locations that are convenient for installation may be locations where attenuation of
ultrasound is not low enough.

In case of through hull
Install the transducer directly to the ship’s bottom
Installation Procedure
(1) Select the installing location.
(2) Remove the fixing nut and one piece of rubber packing.
(3) If the slope of ship’s bottom is greater than 5°, make a wooden base to fit to the slope of ship’s
bottom. To reduce the water resistance, cut the bow direction tip of wooden base at the outer side
of ship’s bottom in the triangle shape.
(4) Make holes at the installing location. If the wooden base is used, make holes in the wooden base.
(5) Thread the rubber packing in the transducer and then the cable.
(6) To prevent water from seeping through the gap between the transducer and the hole, fill out the
gap with FRP or silicon glue. (Glue the wooden base likewise.)
(7) Thread the rubber packing and fix it with the fixing nut firmly.
(8) Connect the transducer cable to the connector of CVS-128 Display unit.
