Garmin eTrex Vista 사용자 설명서

47

The eTrex Vista draws an electronic bread crumb trail 

on the Map Page as you travel along. This bread crumb 
trail is the ‘Track Log’. The Track Log contains informa-
tion about points along its path, including time, and 
position. The eTrex Vista uses this information to allow 
you to navigate using the saved track.

The ‘ TracBack’ feature allows you to return along a 

traveled path without marking any waypoints. When 
you are ready to return to where you started, the eTrex 
Vista takes you back by following the ‘Track Log’ that you 
left behind. You can save a total of ten tracks in the unit 
memory. The Track Log starts recording as soon as the 
unit gets a satellite location fi x and the Track Log feature 
is turned on. When you no longer need a Track Log you 
can press the  on-screen ‘Clear’ button to remove it. This 
also removes the Track Log Pressure or  Elevation Plot.

If you want to keep a record of a certain track log or 

use the ‘TracBack’ feature, clear the Track Log before you 
start traveling. The percentage of memory used by the 
current track log displays at the top of the page. After the 
Track Log is ‘Cleared’, it displays zero percent. When the 
display reaches 100%, the most recent track points start 
to overwrite the least recent if the default setting ‘Wrap 
When Full’ remains selected on the track log setup. To 
avoid losing track points, save the Track Log when it 
approaches the 99% mark.

The Saved Track Page displays the track and it also 

can be displayed on the Main Map Page as you navigate.

The ‘TracBack’ feature allows you to retrace your 

track in both directions. Tracks are marked BEGIN and 
END.

You can set the track recording interval to change 

based on Distance (from 0 to 9.99 miles), Time (up to 99 
hours, 59 minutes, and 59 seconds), or Automatic ( More 
Often, Normal, Less Often, or Least Often).

Use the Options Menu to delete all saved tracks.
