Track Method
The stored track method determines how often posi-
tions are stored in the track log. The default setting is
automatic, which will store a track based on resolution.

memory and provides the most accurate TracBack route.
To change the method to record points based on a
specific time interval:
1. Highlight the ‘CRITERIA’ field, and press
E
.
2. Select ‘TIME INTERVAL’, and press
E
twice.
3. Enter a value in hours, minutes, and seconds, and
press
E
.
Track Log Display
The track log option sets the number of points the
unit will attempt to display on the map page. The default
setting of 250 points provides good resolution with min-
imal screen clutter. The maximum setting is 768 points.
Once you’ve reached the maximum number of track
points, the older points will be lost as new points are
added. Note that adjusting the track points displayed will
not affect whether the receiver records a track log or the
ability to create a TracBack route.
Managing and Clearing the Track Log
The rest of the track setup window displays the percent-
age of available memory currently used to store track log
data and function fields to clear the track log memory and
activate the TracBack feature.
To clear the track log:
1. Highlight ‘CLEAR LOG?’, and press
E
.
2. Highlight ‘Yes?’, and press
