Managing and Clearing the Track Log
The rest of the track setup window displays the per-
centage of available memory currently used to store

track log memory and activate the TracBack feature.
To clear the track log:
1. Highlight ‘CLEAR LOG?’, and press
E

Note: It’s a good idea to clear the track log at the
end of the trail head, etc., in order to make the best use
of the TracBack feature.

pages in their respective sections. Let’s review the rest of
these pages in the order they appear on the Menu Page.

Distance and Sun Calculations
The distance and sun calculation page will give you
the distance and bearing between any two waypoints or
between your present position and a waypoint. It will
also calculate the sunrise and sunset (in local time) for a
particular date at either your present position or any
stored waypoint.
To perform a distance and sun calculation:
1. Highlight the ‘FROM’ field, enter the desired waypoint,
and press
E
.
2. Highlight the ‘TO’ field, enter the destination waypoint,
and press
E
.
3. The ‘DATE’ field will become highlighted. Enter the
date you’ll arrive at your destination, and press
E
.
If you haven’t marked your present position as a
waypoint or you leave the ‘TO’ field blank, the sunrise
and sunset at your present position will be shown.
