3.5 ALARM Menu
The ALARM menu sets the parameters for the tide speed and tide direction alarms, ship’s
speed alarm and trip distance alarm. When an alarm setting is violated, the audible alarm
sounds and a warning message (flashing) appears. To silence the audible alarm, press the
CursorPad. The alarm message remains on the screen until the cause for the
corresponding alarm is eliminated or the alarm is disabled. When the alarm is again violated,
the alarm message appears and the audible alarm is released.
The audible alarm and alarm message may be enabled or disabled independently. Alarm
messages appear in paragraph 4.5.
Note:
Alarm priority is in the order the alarms appear on the ALARM menu; highest priority
is layer 1 and lowest priority is the trip alarm. When multiple alarms are violated, the
audible and visual alarms are given to the alarm having the highest priority.
