Track Setup Page
The track setup page lets you manage the GPS
12XL’s track log data. You can also select whether to
record a track log and define how it is recorded.
To turn the track log on or off:
1. Highlight the ‘RECORD’ field, and press
E
.
2. Select ‘OFF, FILL, or WRAP’, and press
E
. (Note:
Turning the track recording off will prevent using
TracBack).
Track Method
The stored track method determines how often
positions are stored in the track log. The default setting
is automatic, which will store a track based on resolu-
tion. This setting gives the most efficient use of track
memory and provides the best TracBack route.
To change the method to record points based on
a specific time interval:
1. Highlight the ‘METHOD’ field, and press
E
.
2. Select ‘TIME INTERVAL’, and press
E
twice.
3. Enter 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 minimal screen clutter. The maximum setting is
1024 points. Once you’ve reached the maximum num-
ber 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.

Setup
Entering a time interval in
to the track recording cri-
teria will plot your posi-
tion points further apart
than they would be in the
‘Automatic’ setting. This
will increase the distance
you can travel without
using up your track log,
but will greatly reduce the
effectiveness of TracBack.
