In the Chart and Nav panels, you can save a waypoint at the vessel
position, when the cursor is not active, by selecting the new
waypoint option in the menu.
Adjusting the radar image
You may be able to improve the radar image by adjusting the radar
sensitivity, and by filtering out the random echoes from sea and
weather conditions.
You can also adjust the image settings from the radar menu.
Directional clutter rejection
(Broadband 4G Radar only)
This mode automatically works when GAIN = AUTO and SEA =
HARBOR or OFFSHORE. The purpose is to allow smaller vessels to be
seen in the leeward direction of the sea clutter. The GAIN of the
radar receiver is increased dynamically during the sweep, in the
leeward direction, for increased target sensitivity in heavier sea
states.
When GAIN or SEA = MANUAL, the Directional Clutter Rejection
mode will be OFF (non-directional).
In addition, CALM, MODERATE or ROUGH STC Curve settings are
available in the Radar options menu to better optimize the radar
image to your liking.
Gain
The gain controls the sensitivity of the radar receiver.
A higher gain makes the radar more sensitive to radar returns,
allowing it to display weaker targets. If the gain is set too high, the
image might be cluttered with background noise.
