Garmin GNC 300 - Manual (Page 58)

The second page available from the GNC 300’s WPT key is the proximity way-
points page. This page allows you to define an alarm circle around a selected waypoint
and is useful in defining alarm circles around towers or obstructions. Up to nine prox-
imity waypoints can be entered, with an alarm radius of up to 99.9 nm.

twice and use

If two proximity waypoints are entered and their regions overlap, you will be
informed with the message ‘Proximity overlap’. This message will be displayed each time
you turn on the GNC 300 for as long as the overlap remains. Warning: If you enter the
overlap area you will only be informed of the nearest proximity waypoint.
To remove a waypoint from the proximity waypoints page:
1. Press
C
twice, if necessary, to obtain a cursor in the GPS window.

direction to scroll to view additional waypoints, if available.
