Range Rings, Gain, Anti-Sea Clutter (STC), Anti-Rain Clutter (FTC)

Markers (VRM). 
Gain 
The percentage listed next to Gain, displays the current Gain setting 
for your radar display. 
NOTE: 

When adjusting Gain back to a useable level, increase the level un-
til you see a light peppering on the display. Also remember, you will 

have to adjust gain every time you change ranges.

The Range Ring display in the upper left-hand corner of the radar dis-

play shows the current range ring setting. In the example above, Range 

is .5 nautical miles. The Range Ring setting (the distance between each 
ring) is .125 nautical miles.
