PLOTTER-RELATED ALARMS
9.1 Arrival/Anchor Watch
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. The anchor watch
alarm sounds to warn you that your boat is
moving when it should be at rest.
When the arrival or anchor watch alarm is
violated, the audible alarm sounds and the
alarm icon and the indication ARR or
ANCHR appear. You may silence the alarm
with the CLR key. The indication remains on
the screen until the cause of the alarm is cor-
rected.
