When using a GMR xHD radar, the last gain and clutter settings configured for use in any radar mode are
applied to the Radar Overlay automatically. For example, if the gain for the Harbor mode is set to 50%, the
gain for the Radar Overlay is set to 50% automatically. Later, if the gain for the Offshore mode is set to 40%,
the gain for the Radar Overlay is set to 40% automatically.

Automatically Adjusting Gain on the Radar Screen
Auto is the default value for the gain setting. The automatic gain setting for each radar mode is optimized for
that mode, and may differ from the automatic gain setting used for another mode.
Note: Depending upon the radar in use, the gain setting configured for use in one radar mode may or may
not be applied to other radar modes or to the Radar Overlay (
).

changing conditions.
