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.
