information for the next waypoint is displayed.
Advance
While the Waypoint Advance alarm is sounding, Track mode is
suspended and the ST4000 Plus maintains the current boat heading.
1. Check that it is safe to turn onto the new track.
2. Press the track key. This will cancel the Waypoint Advance alarm
and turn the boat towards the next waypoint.
Unless the Waypoint Advance is accepted in the above manner, the
alarm will continue to sound and the current heading will be
maintained.
Dodges
Full control is still available from the keypad when the autopilot is in
Track mode.
Initiating a dodge manoeuvre
In track mode, dodge manoeuvres are accomplished by simply
selecting the desired course change using the course change keys
(-1, +1, -10 or +10).
Ca nce l l i n g a dodge ma noe uv r e
Once the hazard has been avoided, the course change selected for the
dodge manoeuvre should be cancelled by selecting an equal course
change in the opposite direction.
Note: Provided the vessel remains within 0.1†nm of track, there is no
need to steer back towards the track.
