Target expansion
Target expansion will override and increase the default radar pulse length, providing larger
target returns.
Target trails
You can defi ne how long time the trail that each target leaves should remain on your radar
panel. You can also turn OFF target trails.
 Note: True motion is recommended when using Target trails
Clearing target trails from the panel
When target trails are displayed on the panel, the radar menu will be expanded to include an
option where you can clear target trails from your radar panel temporarily. The target trails will
start to appear again unless you switch them off as described above.
The radar palette
Diff erent colors (palettes) can be used to represent detail on your radar panel.
Radar orientation
Radar orientation is indicated on the upper left corner of the radar panel as either HU
(Heading UP), NO (North Up) or CU (Course up).
Heading up
Rotates the radar image to display the current heading directly up on the radar image.
North up
Rotates the radar image with the north direction upwards.
Course up
Rotates the radar image to display the current navigation course directly up.
This option works only when the NSS is navigating an active route. If you are not navigating
an active route the heading up orientation will be used until the navigation function is
started.
Fast scan
(Broadband Radar™ only).
Increases the speed of the radar scanner when the range is set to 2 nm or less. This option
gives faster updates on target movements within this range.
STC curve
(Broadband Radar™ only).
The STC (Sensitivity Time Control) controls the sensitivity of the radar signal close to your
vessel. Your selection should be based on the current sea conditions.
