Once a waypoint is deleted from the list, it cannot be recovered from the unit. It is
advisable to backup important waypoints to a computer using an optional PC cable and
interface software, save them to a data card, or write them down by hand.

3. Press the
ENTER key to confirm the deletion warning.
To delete waypoints by symbol:

ENTER.

Proximity Waypoint List
The ‘Proximity’ submenu of the Points tab lets you define an alarm circle around a stored waypoint
position, and can be used to help you avoid reefs, rocks, or restricted waters. Up to ten waypoints may
be listed, with a maximum alarm radius of 99.99 nautical or statute miles or kilometers. If a proximity
alarm circle overlaps with an existing alarm circle, the message ‘Proximity Overlaps Another Proximity
Waypoint’ appears. Since 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.
