STC curve
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.
¼¼ Note: When a 4G broadband radar is installed, beam sharpening is enabled, resulting in 2X the azimuth resolution — similar to a three- foot length array.
Target trails
Turns on/off shaded echoes of each radar target making it easier to assess the movement of targets relative to your position.
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.
Palette
Different colors (palettes) can be used to represent detail on your radar panel. You can select palettes from the Radar settings menu.
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 so North is always at the top of the screen.
¼¼ Note: You must have a heading sensor connected to your system to use North up mode.
Course up
Rotates the radar image to display the current navigation course directly up. This option works only when the unit 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.
