There are four alarm conditions which gen-
erate both audible and visual alarms: Arrival
alarm, Anchor watch alarm, Speed alarm,
and XTE (Cross Track Error) alarm.
When an alarm setting is violated, the buzzer
sounds, and the name of the offending alarm
and the alarm icon appear on the display.
You can silence the buzzer and remove the
alarm name indication by pressing any key
but the alarm icon remains on the screen until
the reason for the alarm is cleared.
You can also see which alarm(s) is sound-
ing by displaying the MESSAGE board. The
keying sequence is [MENU] (twice), select
MESSAGES and press the [ENT] key. (The
message board is explained in 8.2 Display-
ing the Message Board.)
