Trail Options
This menu lets you change the way the trail updates occur. The options are automatic, time, or distance. When it’s in the auto- matic mode, the unit doesn’t up- date the plot trail while you’re trav- elling in a straight line. Once you deviate from a straight line, the unit “drops” a plot point onto the trail. This conserves plot trail points. If a plot trail uses all of the
available points allotted to it, the beginning points are taken away and placed at the end of the trail.
New Trail
To create or delete a trail select “New Trail”. The screen at right appears. The name, maximum number of points in the trail, ac- tivity, and visiblity are all changed on this screen. Simply highlight the section you wish to change using the arrow keys, then select (or change) it by pressing the ENT key. Press the EXIT key to erase this menu.
Delete All Trails
To remove all of the trails from memory, select “Delete All” from the “Trails” menu. A menu appears asking if you wish to delete all trails. Select “Yes” if you wish to delete all of the trails. The unit will delete all trails and return to the “Trails” menu.
