Manually clearing alarms
Alarms that aren't auto-clearing stay onscreen until you've
cleared them at the ALARMS screen. You display and clear all
manually clearing alarms in the same manner:
1. To display the new alarm, press the STAR key until you
reach the ALARMS screen.
The new alarm is displayed in the NEW ALARMS box.
2. To clear the alarm message from the screen and stop the
alarm audio (if on), press the CLEAR ALARM key.
The new alarm is moved to the OLD ALARMS box.
For a description of auto-clearing alarms and ones that require
manual clearing, see "Table 8: 961/962 alarms" below.
The following abbreviations are used in Table 8.
For alarms, 'NAME' = name of waypoint
For color, G = green, R = red, Y = yellow
For manually clearable, N = no, Y = yes
For priority, L = low, M = medium, H = high, VH = very high
