Alarms
This unit has several GPS alarms. By default, all the alarms are turned
on with the exception of the anchor alarm. You can turn the 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 .1 mile, then the alarm will flash a
message when you come within .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. For example, if the
alarm is set to .1 mile, then the alarm flashes a message if you drift .1
miles to the right or left of the line to the waypoint.
The anchor alarm is triggered when you drift outside of a preset radius.
Using the .1 mile as an example, if you're anchored and the boat moves
more than .1 miles, a tone will sound and a message will appear.
