Furuno gp-31 Manuel D’Utilisation

There are seven alarm conditions which
generate both aural and visual alarms: Ar-
rival  alarm, Anchor  watch  alarm,  XTE
(Cross-Track Error) alarm, Speed alarm,
DGPS alarm, Time alarm, and Trip alarm.

When an alarm setting is violated, the
buzzer sounds, and the name of the offend-
ing alarm and the alarm icon appear on the
display. You can silence the buzzer and
remove the alarm name indication by press-
ing any key; the alarm icon remains on the
screen until the reason for the alarm is
cleared.

You can see which alarm(s) is sounding by
displaying the message board by the fol-
lowing keying sequence: [MENU] (once or
twice) MESSAGE, [ENT]. The message
board is discussed in paragraph 8.2 “Dis-
playing the Message Board.”

You may activate the arrival alarm or the
anchor watch alarm; they cannot be acti-
vated together.

The arrival alarm informs you that own ship
is approaching a destination waypoint. The
area that defines an arrival zone is that of
a circle which you approach from the out-
side of the circle. The alarm will be released
if own ship enters the circle.

1. Press the [MENU] key once or twice to

open the menu.

2. Select ALARMS.

3. Press  the  [ENT]  key. The ALARMS

menu appears.
