Radar

When using a GMR 604 xHD, 606 xHD, 1204 xHD, or 1206 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.

The chartplotter sets the gain automatically once, based on average conditions, the range 

of the radar signal, and the selected radar mode. The chartplotter does not readjust the gain 

automatically in response to changing conditions.
