Alarms
This unit has several GPS alarms. The factory default setting has all
alarms turned on, but you can turn alarms off and on and change their
distance settings.
You can set an arrival alarm to flash a warning message and sound a
tone when you cross a preset distance from a waypoint. For example, if
you have the arrival alarm set to 0.1 mile, the alarm will flash a mes-
sage when you come within 0.1 mile of the recalled waypoint.
The off-course alarm warns you when your track drifts too far to the
right or left of the course line to the waypoint. If the alarm is set to 0.1
mile, an alarm message will flash if you drift 0.1 mile or more to the
right or left of the line to the waypoint.
The anchor alarm is triggered when you drift outside of a preset radius.
If you're anchored and your boat moves more than 0.1 mile, an alarm
message will flash and a tone will sound.
You can only adjust alarm distance settings or turn alarms off or on in
Advanced Mode.
