3.7 Setting Alarms

The

NAV

398 has three operator programmable alarms that you can set to

advise you when limits have been reached. The types of alarms available

are:

ARRIVAL- Arrival at a waypoint.

ANCHOR Exceeds Anchor drift limit.

OFF COURSE- Straying too far from track.

Whenever an alarm is set and activated, the audible beeper will sound and

the alarm characters will blink on-screen. You can set an Arrival alarm or
Anchor alarm, but not both types together. Press

to silence

the audio alarm.

3.7.1 The Arrival Alarm

The Arrival alarm can be set to alert

you when you are within a specified

distance from your waypoint. The ar-
