WARNING:
If you uncheck the Update Trail option, automatic trail
creation and recording will be turned off. You must turn
it on to record trails. The default setting is on.
Update Trail Criteria
The options are automatic, time or distance. When it is in the default
mode, the unit does not update the plot trail while you are traveling 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 the available points allotted to it, the beginning points are
taken away and placed at the end of the trail.
From the Trails Menu, press to
OPTIONS|ENT. Select one of the three
Update Criteria options — Auto, Time or Distance — and press
ENT.
Trail Update Rate
A trail updated by time has a range of 1 to 9999 seconds. The default is
3 seconds. The range for updating a trail by distance is 0.01
mile/nm/km to 9.99 mile/nm/km. The default is 0.10 mi.
When time or distance are chosen as the update criteria for a trail, a
dialog box will appear, allowing you to input the desired update rate or
distance. Select the dialog box and press
ENT. Use to change the
first character, then press to the next character and repeat until the
entry is correct. Press
EXIT to return to the Trail Options Menu.
Update Rate setting (left) and Update Distance setting (right).
