noise rejection capability in a deep depth are established. The auto mode function provides the best
image.
The high-performance LCD maint ains high visibility under any conditions.
The unit can be installed in an open b rid ge and is highly waterproof.
Sona-Tone (Sonar sound) functio n is equipped with for catching situations schools of fish and
others by sound.
Up to 10 images can be stored. If you connect the optional GPS, the fishing hot spot function, that
directs your boat to navigate easily to the location desired, is available by marking the event mark
when recalling the stored image.
With the adoption of a specific filter (AR coat), an image can be seen clearly, refusing sunshine.
The countermeasures against the reflection on the LCD screen and dew are provided.
The various alarm functions are available. (Bottom, scho ol of fish, water tempe rature*, boat speed*,
arrival*, XTE*, power) (Note: The mark * denotes that the connection of option is mandatory)
When flush-mounting, the unit can be easily installed from front side.
The RGB output for an external monitor is provided a s standa rd eq uipment. The use of the external
monitor enables you to observe easily the echo sounder scree n at a location which is remote f rom a

Caution: Gain (TD) setting value widely
varies upon installation conditions
such as material of hull and
installation method. Low frequency
(50 kHz) may not be used due to large
signal attenuation in some cases.
TVG
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.
The deeper the depth is, the weaker the
reflected signal of echo sounder becomes due
to attenuation. Thus, comparing the signal
reflected from the fish of the same size, 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.

Flush-mount Installation
(1) Make a square hole at the location to be installed. (See Fig. 5.5.)
(2) Turn counter-clockwise the knob bolt fixing the display unit to the mounting bracket to loosen it,
push the unit to the left side and pull the unit upward. The mounting bracket and knob bolt are not
used.
(3) Confirm that the unit matches with the square holes. If not matched, correct the square hole.
(4) Remove the front frame of the display unit, pulling it toward you. (See Fig. 5.4.)
(5) Connect the connectors for power and transducer to the unit respectively.
(6) Install the display unit in the installing location (square hole) and fix it with four tapping screws
(4mm) (M4 or pan-head). (Prep are 4mm screws suitable for thickness of installing location.)
(7) Install the front frame removed in step (4).

5.3 Installation of Transducer
The standard installation of the transducer is shown in figure 5.6.
Figure 5.6 Installation of T r ansducer
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: It is strongly recommended to confirm the location of the installation of Inner-hull
with the ship manufacturer. The Inner-hull device is more simplified method. The gain
falls dramatically in comparison with the Through -hull performance. Low frequency (50
kHz) may not be used due to large signal attenuation in some cases. Depth range
performance using 200 kHz Transducer in case of Inner-hull can be less about 50% than
that of Through-hull.
Caution: Fishing boats may have structure with FRP contained air bubbles and foamed
materials that would prevent ultrasound from penetration. Therefore, the location
convenient for installation may not be locations where attenuation of ultrasound is 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 resista nce, cut the b ow 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 Display unit.
