Radar: Gain adjustment
You can use the radar gain to adjust the sensitivity of the radar.
The radar gain should be set so that background noise is just
visible on the
Radar screen. The radar gain is shown as a
percentage.
If the radar gain is too low, weak echoes won't be shown. If the
radar gain is too high, strong echoes will be difficult to see
amongst the large amount of background noise.
Any changes are global and apply to all the
Radar screens.
If the radar gain mode is set to Auto and you adjust the gain
setting manually, the radar gain mode is changed to Manual.

To change the radar gain setting:
• Display the Radar screen and main menu. If you can't see the
Adjust Radar button, select Return.
• Select
Adjust Radar.
• Select
Gain and a slider box appears. The current setting is
shown as a line within a solid bar of color and as a percentage.
• Drag the line to change the setting.
• Select
OK.

displayed. If the sea clutter setting is too high, there's a chance
that you'll lose small targets.
The sea clutter adjustment is shown as a percentage. 0% is the
default.
If the sea clutter mode is set to Auto and you adjust the sea
clutter setting manually, the sea clutter mode is changed to
Manual. This applies to all the
