31Activating a TracBack will create aroute base on your current tracklog. ‘T’ waypoints and symbols willbe added to the waypoint list anddisplayed 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 bottomof the active route page and pressENTER. Highlight ‘YES’ on thewarning page and pressENTERagain to confirm.Tips On the TracBack Feature• Always clear your track log at the exact point thatyou want to go back to (trail head, truck, etc.).• The ‘RECORD’ option on the track log setuppage must be set to ‘WRAP’ or ‘FILL’.• There must be at least two track log points storedin memory to create a TracBack route.• If there is not enough available memory to addmore waypoints and create a TracBack route, youwill be alerted with a ‘waypoint memory full’message, and the receiver will use any availablewaypoints 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 setuppage is set to a time interval, the TracBack routemay not follow your exact path. (Keeping the cri-teria set to automatic will always provide the mostdetailed TracBack route.)• If the receiver is turned off or you lose satellitecoverage during your trip, the TracBack route willsimply draw a straight line between any pointwhere coverage was lost and where it resumed.• If the changes in direction and distance of yourtrack log are complex, 30 waypoints may not beenough to accurately mark your exact path. Thereceiver will then assign the 30 waypoints to themost significant points of your track, and simplifysegments with fewer changes in direction.• To save a TracBack route, copy route 0 to an openstorage route before activating another TracBack.Activating another TracBack or storage route willoverwrite the existing TracBack route.• Whenever a TracBack route is activated, the re-ceiver will automatically erase any temporarywaypoints (‘T###’) that are not contained in routes1-19. If there are temporary waypoints stored inroutes 1-19, the receiver will create any new temporary way points using the first three-digit num-ber available. (You can also quickly delete all tem-porary TracBack waypoints in memory by usingthe ‘DELETE BY SYMBOL’ method described onpg. 27.)REFERENCETracBackTips
