1.7 Receiver Sensitivity
The [GAIN] key adjusts the sensitivity (gain)
of the receiver. It works in precisely the same
manner as the volume control of a broadcast
receiver, amplifying the signals received.
The sensitivity is adjusted automatically
according to sea conditions, and you may
also further adjust it manually to fine tune.
The proper setting is such that the
background noise is just visible on the
screen.
If you set up for too little sensitivity, weak
echoes may be missed. On the other hand
excessive sensitivity yields too much
background noise; weak targets may be
missed because of the poor contrast between
desired echoes and the background noise on
the display.
1. Press the [GAIN] key consecutively until
the display shown below appears.
