2.4 SENSITIVITY ADJUSTMENT
Sensitivity can be adjusted.
Adjust the noise on the display unit to achieve better observation state.
CAUTION
If sensitivity is set too high, unnecessary signals such as noises in
the receiver and false echoes increase to lower target visibility.
At the same time, if sensitivity is set too low, detection of targets
such as ships and dangerous objects may be hindered.
Therefore, sensitivity must always be set to an optimal level.
Noise Adjustment
1 Turn the [GAIN] control.
Turn the [GAIN] control clockwise to increase sensitivity.
Turn the [GAIN] control counterclockwise to decrease sensitivity.
The sensitivity adjustment screen appears when turning the [GAIN] control.
Sensitivity can be adjusted between 0 and 100.
When turning the [GAIN] control, the gain control indication is stretched or shrunk.
