3.11.2 Arrival alarm
The arrival alarm informs you that your boat is approaching a destination
waypoint. The area that defines an arrival zone is that of a circle which you
approach from the outside of the circle. The alarm will be released if your boat
enters the circle. When the arrival alarm is active a red dashed circle marks the
arrival alarm area. Note that the arrival alarm and anchor watch alarm can be
turned on together.
