128 C-Series Display Reference Manual
Course Up (C-UP)
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 prioritizes 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.
Note:
If heading data becomes unavailable whilst in this mode, a warning message
will be shown, the status bar indicates the Course Up in brackets and the radar uses 0°
heading in relative motion. When heading data becomes available once more, Course-
Up mode is reinstated.
To select the orientation mode:
The selected motion mode is displayed in the status bar.
Setting the motion mode
The motion mode controls the relationship between the radar and your boat. There are
two modes:
• Relative motion.
• True motion.
The selected motion mode is displayed in the status bar. The default setting is relative
motion with zero offset
