Tips on Creating and Using the TracBack Feature

The GPSCOM 190’s TracBack feature is designed to

help you quickly create and activate a route that follows

your path back to a user-defined starting point. To get the

most out of the TracBack feature, remember the following

tips;

• Always clear your track log at the exact point which

you will want to go back to (airport, landing field,

etc.),

• The ‘RECORD’ option on the track log setup page

must be set to the ‘Yes’ position,

• There must be at least two track log points stored in

memory to create a TracBack route,

• If there are not enough available waypoints in

memory to create a TracBack route, you will be

alerted with a ‘waypoint memor)'^ full’ message. The

receiver will use any available waypoints to create a

TracBack route with an emphasis on the track log

closest to the destination (the oldest track log point

in memory).

• II the ‘CRITERIA option on the track log setup page

is set to a time interval, the TracBack route may not

follow your exact path (keeping the criteria set to

automatic will always provide the best TracBack

route).

• If the changes in direction and distance of your

track log are very 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.

• If you want 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 receiv

er will automatically erase any temporary way-

points (e.g., ‘TOOT) 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 waypoints using the first three-digit number

available.
