Gain
Gain controls the sensitivity of the Radar receiver. Auto (default) is the

receiver sensitivity by selecting a higher gain. If there is too much detail, or the
screen is cluttered, lower the sensitivity (lower the gain) to increase the clarity of
the screen.
Sea Clutter
Sea Clutter controls unwanted screen clutter caused by choppy sea conditions.
The slider has three preset positions: Calm, Moderate, and Rough.
Rain Clutter
Rain Clutter controls unwanted screen clutter caused by rain at close ranges (use
the slider to select 1-100%).
FTC (Fast Time Constant)
FTC controls unwanted screen clutter caused by rain at a distance. The Fast Time
Constant has four settings: Off, low, Medium, and high.
