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
