Tips On the TracBack Feature
• Always clear your track log at the exact point that
you want to go back to (trail head, truck, etc.).
• The 'RECORD' option 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, and the receiver will use any available
waypoints to create a TracBack route with an em-
phasis on the track log closest to the destination
(the oldest track log point in memory).
• If the 'METHOD' option on the track log setup
page is set to a time interval, the TracBack route
may not follow your exact path. (Keeping the cri-
teria set to automatic will always provide the most
detailed TracBack route.)
• If the receiver is turned off or you lose satellite
coverage during your trip, the TracBack route will
simply draw a straight line between any point
where coverage was lost and where it resumed.
• If the changes in direction and distance of your
track log are complex, 30 waypoints may not be
enough to accurately mark your exact path. The
receiver will then assign the 30 waypoints to the
most significant points of your track, and simplify
segments with fewer changes in direction.
• To save a TracBack route, copy route 0 to an open
storage route before activating another TracBack.
Activating another TracBack or storage route will
overwrite the existing TracBack route.
• Whenever a TracBack route is activated, the re-
ceiver will automatically erase any temporary
waypoints ('T###') that are not contained in routes
1-19. If there are temporary waypoints stored in
routes 1-19, the receiver will create any new tem
porary way points using the first three-digit num-
ber available. (You can also quickly delete all tem-
porary TracBack waypoints in memory by using
the 'DELETE BY SYMBOL' method described on
pg. 27.)

Tips
Activating a TracBack will create a
route base on your current track
log. 'T' waypoints and symbols will
be added to the waypoint list and
displayed on the map for easy iden-
tification. The TracBack will be-
come the 'Active Route' and dis-
played on the active route page.
To cancel an active TracBack, high-
light the 'CLR' field at the bottom
of the active route page and press
ENTER . Highlight 'YES' on the
warning page and press ENTER
again to confirm.
