Resolution— records track plot based upon a user-defi ned variance from your course over
ground. The resolution option is the default setting and is recommended for the most
effi cient use of memory and TracBack performance. The distance value (entered in the value
fi eld) is the maximum error allowed from the true course before recording a track point.
• Value— defi nes the distance or time used to record the track log.
• Save— allows you to save the current active track log.
• Erase— allows you to clear the active track log currently stored in memory.
For the ‘Saved’ tab, the following menu options are available:
• Review On Map— displays the saved track log on a Track Map page.
• Delete Track— deletes highlighted saved track log from memory.
• Delete All— deletes all saved track logs from memory.
