1. OPERATION
16
[TX Power] : Interference may appear on the
screen when an echo sounder having the
same frequency as your own is being operat-
ed in the vicinity of your vessel. In this case,
lower your TX power and contact the vessel to
request them to reduce their TX power. The
higher the numeric the greater the TX power.
The [Auto] setting automatically adjusts TX
power with depth.
[TX Rate] : Change pulse repetition rate. Nor-
mally, the highest rate (10) is used. When in
shallow waters second reflection echoes may
appear between the surface and actual bot-
tom echo. In this case, lower the TX rate level.
The setting [MAX] automatically adjusts the
frequency and pulse length with depth. The
[S] setting, which requires speed data, selects
the TX rate according to your boat’s speed. A
high rate for fast speed; a slow rate for slow
speed.
