3.2 Stopping, Restarting Plotting of Own Ship Track
When your boat is at anchor or returning to port, you probably won’t need to
record its track. You can stop recording the track, to conserve the track memory,
as follows.
1. Press the [PLOT INTVL] key several times to show the “H” (Hold) icon (at the
bottom of the screen). Each time the key is pressed the track function
available changes in the sequence shown below.
TRACK INTERVAL 1 -> TRACK INTERVAL 2 -> HOLD -> TRACK INTERVAL 1
Track plotting interval or “HOLD” appears at the top right corner of the NAV INFO
1 (or 2) display. When plotting is stopped, own ship’s mark changes from a solid
circle to a hollow one and track is not stored in the memory.
