RadarSensitivity controlsThe Sensitivity controls available are dependant upon the Radar scanner in use.
| Control | Name | Description |
|---|---|---|
 |
‘G’ GainRadarGain | The control determines the signal strength at which target returns are shown onscreen. The Gain control can be set to Auto or Manual. A higher value produces more target returns and noise onscreen. |
 |
‘R’ RainRadarRain | 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 object. The higher the Rain control is set the more echoes will be suppressed. |
 |
‘S’ SeaRadarSea | 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 GainRadarColor 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. The control can be set to Auto or Manual. |
