Arrival
As the boat arrives at the target waypoint the navigation aid should
manually or automatically select the next target waypoint. The
ST4000+ will then detect the new target waypoint number, sound the
Waypoint Advance alarm and display the Waypoint Advance screen.
This shows the new bearing to the next waypoint and the direction the
boat will turn to acquire the new track.
Advance
When the ST4000+ sounds the Waypoint Advance alarm, it suspends
Track mode and maintains the current boat heading.To advance to the
next waypoint:
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.
Note: If you do not press track to accept the Waypoint Advance, the
ST4000+ will maintain the current heading and continue sounding
the alarm.
