edged. Each successive press of
Clear alarm
will show you the most recent alarm
message from each category.
Clearing alarms
Clearing an alarm means removing the
flashing alarm icon as well as the word
new
from the display of that alarm on the
Alarms
screen. To manually clear an alarm
(and to see other alarms that may need
clearing), press the
Clear alarm
key on the
Alarms
screen.
There are two types of alarms:
•
Auto-clearing alarms automatically
clear after the alarm condition
disappears, or in some cases, after a
short time-out period (typically about
10 seconds). Most alarms are
auto-clearing; however, they can also
be manually cleared, if desired.
•
Alarms that require manual clearing
stay on-screen until you clear them on
the
alarms
screen. Some serious alarms,
such as loss of position fixes, will repeat
at intervals.
All of the 972’s alarms are described in
Table 3 below.
