7. ALARMS
7.1 Overview
There are seven alarm conditions which gen-
erate both aural and visual alarms.
When an alarm setting is violated, the buzzer
sounds and the name of the alarm being vio-
lated appears on the display. The alarm icon
also appears on the Plotter 1, Plotter 2 and
Highway displays. This occurs on both navi-
gators 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.
