9. PLOTTER ALARMS
9.1 Introduction
There are five plotter-related alarms which
generate both audible and visual alarms: Ar-
rival alarm, Anchor Watch alarm, XTE (Cross
Track Error) alarm, Proximity alarm, and
Speed alarm.
When an alarm setting is violated the buzzer
sounds, and the speaker icon (
) appears
in red. You may silence the alarm by press-
ing the [CLEAR] key. The icon remains on
the screen until the cause of the alarm is re-
moved or the alarm is deactivated.
9.2 Audio Alarm On/Off
The audio alarm sounds whenever an alarm
setting is violated. You can enable or disable
the audio alarm as follows:
1. Press the [ALARM] key to show the alarm

9.3 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 ar-
rival alarm area.
