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.
