against short range echoes. Note that this func-
tion is operative when manual is selected on the
GAIN knob.
Smoothing: Smoothes echo presentation
when enabled. Adjust the setting when echoes
appear “spotty”.
TX Power: Interference may appear on the
screen when an echo sounder having the same
frequency as your own is being operated 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. Note that this function is only operative
when Fish Info and Fish Symbols in the Display
menu are off. When Fish Info and Fish Symbols
are on, the TX power mode is “Auto”.
TX Rate: Changes pulse repetition rate. Nor-
mally, the highest rate (10) is used. When in
shallow waters second reflection echoes may
appear between surface and actual bottom
echo. In this case, lower the TX rate level.
The choice "S" means the ship's speed depen-
dent mode, where the TX rate changes auto-
matically with ship's speed. (Requires ship's
speed input.)
