Automatic Acquisition
Automatic acquisition can only be achieved if the pilot is receiving
cross track error and bearing to waypoint information (via SeaTalk or
NMEA 0183). It is initiated as follows:
1. Bring the vessel to within 0.1 nm of track.
2. Press auto.
3. Press track to enter Track mode, with the current locked heading
displayed.
After a short delay for data acquisition, the Waypoint Advance alarm
will sound, and the display will show the current bearing to waypoint
alternating with the direction in which the boat will turn.
Note: If the vessel is further than 0.3 nm from the track, the Large
Cross Track Error alarm will sound. Press
standby to cancel the
alarm, hand steer closer to the track, and press auto and track again.
4. Check that it is safe to turn onto the new course.
5. Press the track key. The boat will turn on to the new course and
the alarm will be cancelled.
