7. ALARMS
7.1 Overview
There are seven alarm conditions which
generate both aural and visual alarms.
When an alarm setting is violated, the buzzer
sounds and the name of the alarm being
violated appears on the display. The alarm
icon also appears on the Plotter 1, Plotter 2
and Highway displays. This occurs on both
navigators when they are sharing data.
Alarm status is output to external equipment
through the DATA1 port and the DATA4 port
when it outputs data in NMEA format.

on both navigators when they are sharing
data.
