of the screen, and enter the warning radius—up to 4.9 nm.
4. Press the ENTER key.
If you've made a waypoint into an avoidance area, the 958 will
sound an alarm when you enter that area, but only if you've
turned on the alarm.
To set the audible avoidance-area alarm:
1. Press the STAR key to display the ALARMS screen.
2. Press the CURSOR PAD to select the ALARM AUDIO
option.
3. Press the EDIT ALARM menu key.
4. Press the CURSOR PAD to change the setting to ON.
5. Press the ENTER key to make your selection, or CLEAR to
leave it unchanged.
If you want to set the 958's alarm to sound only when you enter an avoid-
ance area, turn off the anchor drag, cross track, arrive radius, and DGPS
alarms. The alarm will now beep only when you enter an avoidance area,
(or when you lose GPS or loran navigation signals, but for no other rea-
son).
