3.2.4 Adjust Gain [GAIN]
See also the Section 3.2.8 "To get the appropriate image that targets can be easily
observed".
Procedures
1) Adjust noise on the radar display by turning the [GAIN] dial until
targets can be easily observed.
Turning [GAIN] dial clockwise increases gain.
Turning [GAIN] dial counterclockwise decreases gain.
If the gain is too high, unnecessary signals including
receiver noise and false images 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.
Be sure to always adjust for the best gain.
Turning the [GAIN] dial clockwise will increase the receiving gain, and the
range to observe radar video is widened. However, if the gain is too high,
unnecessary signals including receiver noise and false images increase
resulting in reduction of targets' visibility.
To observe densely crowded targets or short-range targets, turning the
[GAIN] dial counterclockwise will decrease the receiving gain, which
enables targets to be easily observed. However, caution must be taken so
as not to overlook a small and important target.
