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.”
