Radar Settings Menu - Raymarine Lighthouse Sport 3.10 Series Advanced Operation Instructions

Control Description
'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.
'CG' Color Gain
The control sets the lower limit for the color used for the strongest target
returns. All target returns above this value are displayed in the strongest color.
Those with a weaker value are divided equally between the remaining colors.
All to Auto
Sets all Sensitivity settings to Auto.
