Alarms
Alarms automatically alert you to certain
situations, for example, when you're
approaching a waypoint, or entering an
avoidance area, or when you've lost
position fixes. The 972 displays an alarm in
two ways:
as an alarm icon flashing on the display
•
screen. (For a detailed explanation of
these alarm icons, see Table 3 on page

as an alarm message on the
•
screen
Also, whenever an alarm icon appears on
any screen, an audible alarm will sound if
you've turned on the alarm audio. Each
alarm has a distinctive beep that's based on
Morse code. If you're choosing whether to
keep the alarm audio on or off, remember
that the audio beep may be a necessity
when you're unable to look at the display
screen.
