Track Tab— lets you specify whether or not to record a track log (an electronic ‘breadcrumb trail’
recording of your path), defi ne how it is recorded, or save track log data for future use. The Track Tab
also provides an indicator of the memory used for the active track log and options to clear the track
memory or start a TracBack route. See pages 58-59 for TracBack information. The Track submenu is
divided in two tabs: the ‘Active’ tab and the ‘Saved’ tab.
The ‘Active’ tab is for the active log (the log currently being recorded). It displays track memory
used and current settings.
The ‘Saved’ tab displays and manages a list of any saved track logs, allows TracBack activation and
map display of saved logs. The active log stores up to approximately 2000 track log points, based upon
the criteria specifi ed in the Track settings. Up to 10 track logs may be saved in memory, with up to
250 track log points in each saved log.
For the ‘Active’ tab, the following settings are available:
• Record Mode— lets you select one of three track recording options:
Off— No track log will be recorded. Note that selecting the ‘Off’ setting will prevent you from
using the TracBack feature.
Fill— a track log will be recorded until the track memory is full.
Wrap— A track log will be continuously recorded, wrapping through the available memory
(replacing the oldest track data with new data).
