Alarms

This unit has three GPS alarms: Arrival Alarm, Off Course Alarm and Anchor Alarm — the only one of the three set to Off by default.

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 .1 mile, the alarm will flash a mes- sage when you come within .1 mile of your destination.

The off course alarm warns you when your track drifts too far to the right or left of the course line to your destination. For example, if the alarm is set to .1 mile, then the alarm flashes a message if you drift .1 miles or more to the right or left of the course line.

The anchor alarm is triggered when you drift outside of a preset radius. If you are anchored and your boat moves more than .1 miles, the alarm will flash a message and sound a tone.
