3.2.4 Adjust Gain [GAIN / PL]
CAUTION
If the gain is too high, unnecessary signals including
receiver noise and false video increase resulting in
reduction of visibility of targets.
On the contrary, if the gain is too low, targets including
ships and dangerous objects may not be clearly indicated.
Procedures 1 Adjust noise of the display by turning the [GAIN / PL] dial until targets
can be easily observed.
Turning [GAIN / PL] dial clockwise increases gain.
Turning [GAIN / PL] dial counterclockwise decreases gain.
By increasing receiving gain, the range to observe radar video is widened.
To observe densely crowded targets or short-range targets, reducing the receiving gain will
enable the targets to be easily observed.
It is recommended to restore the setting to the factory default,
if you lost the appropriate settings. The factory default level
is shown on the bar chart as a green line.
Current Position
Default Position
The factory default level is assigned by every function mode.
