Reference
• Always clear the Track Log at the point you want to
return to (your home, your home airport, etc.)
• The ‘Record Mode’ on the Track Log Setup Page
must be set to ‘Wrap’ or ‘Fill’.
• There must be at least two Track Log points stored
in memory to create a TracBack route.
• If there is not enough available memory to add
more waypoints and create a TracBack route, you
will be alerted with a ‘waypoint memory full’
message. The receiver will use the available
waypoints to create a route with an emphasis on the
Track Log closest to the destination. Also, existing
track log waypoints that are not contained in routes
1-20 will be erased to free more memory. The unit
will create the new waypoints using the first
available three-digit number.
• If the Track Log Setup Page’s ‘interval’ field is set to
‘Time’, the route may not follow your exact path.
(Keep the ‘interval’ field set to ‘Resolution’ for best
results.)
• If the receiver is turned off or satellite coverage is
lost during your trip, TracBack will draw a straight
line between any point where coverage was lost and
where it resumed.
• If there are frequent changes in direction and
distance in your Track Log, 30 waypoints may not
accurately depict your exact path. The receiver will
then assign the 30 waypoints to the most significant
points of your Track Log and simplify segments
with fewer changes in direction.
A TracBack route
contains a series of
waypoints labeled ‘T###’
that approximate your
previous route of travel.
‘Wrap’ will overwrite the
old track log data in
memory, once all
memory has been used.
