Item
The various items in the menu are explained.
TVG
The TVG corrects the difference of strength
between echo reflected from the shallow depth
and echo reflected from deep 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 with the signal
reflected from the same size fish in the shallow
depth, the signal reflected from the fish in the
deep depth becomes weak. The TVG corrects
the echo signal reflected from the deep depth to
be equal to that reflected from shallow depth by
increasing the receiver gain so that the effect
that the strength of echo signal reflected from
the deep depth looks same as that reflected
from the shallow depth provided. The correction
gain due to the depth increases in the order of
weak → medium → strong. When set to “weak”,
the TVG also provides the effect that reduces
noise in the shallow depth.

Caution: When set to [OFF], the built-in
speaker does not output the
sonar.
When set to [ON], the built-in
speaker outputs the sonar.

Press the 【MENU】 key to close the
menu.
Connection of External Speaker
Connect the external speaker with amplifier
(option) so that you can hear the sonar easily.
The sonar is always outputted. Adjust the
speaker volume with the volume provided on
the speaker.
Caution: The external speaker is an option.

The strength of transmission output (power)
can be changed.
When the noise of interference with the
neighboring echo sounder occurs, if the powers
of transmission outputs at both sides are
weakened, the interference noise can be
suppressed.
In the [Auto] setting, the transmission output is
automatically adjusted.
