How Do I Set The Motion Mode - Raymarine C-Series Reference Manual

Chapter 5: Using the Radar
This is the default mode for the radar application.
North Up (N-UP)
In North Up mode, the radar picture is fixed with true north upwards. As your boat
changes its heading, the SHM will move accordingly.
Notes: (1) If heading data becomes unavailable whilst in this mode, a warning
(2)
Course Up (C-UP)
In Course Up mode, the radar picture is stabilized and shown with your current course
upwards. As your boat's heading changes, the SHM moves accordingly. If you select a
new course, the picture will reset to display the new course upwards.
The reference used for Course-Up depends upon the information available at a given
time. The system always prioritises this information in the following order.:
1. Bearing from origin to destination, i.e. intended course .
2. Locked heading from an Autopilot.
3. Bearing to waypoint.
4. Instantaneous heading.
If heading data becomes unavailable whilst in this mode, a warning message
Note:
will be shown and the radar uses 0° heading in relative motion. When heading data
becomes available once more, Course-Up mode is reinstated.
