Proximity Points
Use the Proximity Points tab to dene an alarm circle around a
stored waypoint location. The alarm circle can help you avoid reefs,
rocks, or restricted waters. Up to 100 waypoints can be listed with
a maximum alarm radius of 99.99 nautical miles, statute miles, or
kilometers.
If a proximity alarm circle overlaps an existing alarm circle, a
“Proximity Overlaps Another Proximity Waypoint” message
appears. Because the unit only alerts for one of the overlap points,
use caution when navigating in these areas. If you enter an alarm
circle overlap, you are only alerted to the closest proximity
waypoint.
To turn proximity alarms on or off:
1. Highlight the Points tab on the Main Menu, and then select
the Proximity sub tab.
