In fact, some people use this technique to enter new waypoints —they find
it easier to edit an existing waypoint or current position than keying
everything in. There are two ways to do this. You can duplicate a waypoint
as described above and key in edit changes, or you can edit the current
position by pressing
POS, UP ARROW.
Whichever method you choose, be
sure to select a unique nam
e for the new waypoint before editing the position
coordinates.
Waypoints are deleted by pressing
CLEAR
while they are displayed. With
waypoint VNCOUV still an the screen, press
CLEAR.
The receiver displays a
warning, asking if you really want to delete this waypoint. Press the
UP/
DOWN ARROW
to select YES or NO, then press
ENTER.
