Control Description
['G' Gain]
The control determines the signal strength at which target
returns are shown onscreen.
A higher value produces more target returns and noise
onscreen.
['R' Rain]
Precipitation appears on the radar screen as lots of small
echoes which continuously change size, intensity and
position. The rain control suppresses these echoes making
it easier to identify real objects.
The higher the rain control is set the more echoes will be
suppressed.
['S' Sea clutter]
Radar echoes from waves can clutter the radar screen.
The sea control suppresses these echoes (for up to 5 nm
depending on conditions) making it easier to identify real
objects.
The higher the sea control is set the more echoes will be
suppressed.
