TracBack NavigiUioii

Another method of navigating to a destination is by using

the GPS 89’s TracBack feature. The TracBack function allows

you to quickly and easily retrace your path using the track

log automatically stored in the receiver^ memory. The advan

tage of the TracBack feature is to eliminate the need to mark

waypoints along the way and manually create and activate a

route back to where you began your trip.

The TracBack route is created by reducing your current

track log into a route of up to 30 waypoints, and activating

an inverted route along those points. Once activated, a

TracBack route will lead you back to the oldest track log

point stored in memory, so it’s usually a good idea to dear the

existing track /jointfilesconvert/1655666/bg at the start of your current trip before you

take off.

To dear the track log and define a starting point for

a TracBack route:

1. From the menu or map configuration page, highlightthe

TRACK LOG'option.

2. Press A to access the track log page.

3. Use the key to highlight the 'CLEAR LOG?' option.

4. Press The clear log confirmation page will appear.

Use 4 to highlightthe 'YesT prompt and press A.

To activate a TracBack route:

1. From the menu page, highlightthe 'TRACK LOG' option.

2. Press A to access the track log page.

3. ffighlightthe TRACBACK?' tqrtion and press A.

Once the TracBack function has been activated, the GPS

89 will take the track log currently stored in memory and

divide it into segments called legs. Up to 30 temporary way

points (e.g., 'TOOT) will be created to mark the most signifi

cant features of the track log in order to duplicate your exact

path as closdy as possible. A TracBack route from your pre

sent position to the oldest track log point will be created as

the active route (the active route page will appear), and pro

vide steering guidance to each waypoint back to the starting

point of your track tog.
