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

4-30
If heading data becomes unavailable whilst in this mode, a warning message will be
shown and the chart uses 0° heading in relative motion.

How do I set the motion mode?

PRESENTATION...
The motion mode controls the relationship between the chart and your boat. The three
motion modes are:
• Relative motion.
• True motion.
• Autorange.
When you pan the chart, the motion mode is suspended. This is indicated in the status
bar by ( ) around the motion mode and enables you to view another area of the chart
whilst navigating. To reset the motion mode and return your boat to the screen, press
FIND SHIP. Manually changing the range in autorange also suspends motion mode.
The default setting is relative motion with zero offset. The mode that you select is
restored at power up.
Relative motion (RM) with optional vessel offset
When the motion mode is set to Relative, the position of your boat is fixed on the
screen and the chart picture moves relative to your boat.
You can specify using the VESSEL OFFSET soft key, whether the boat is fixed in the
center of the window(0 offset) or offset by 1/3 or 2/3.
