location on the Zone Map.
2. Press and hold the button for more
than 3 but less than 6 seconds,

again will cause the numbers to
increment (Note: they will repeat

the button when the desired Zone
Number appears on the display
will set the new Zone.

pass will start displaying a com-
pass heading again.
There are some conditions that can
cause changes to the vehicle mag-
nets, such as installing a ski rack or
a CB antenna. Body repair work on
the vehicle can also cause changes
to the vehicle's magnetic field. In
these situations, the compass will
need to be re-calibrated to quickly
correct for these changes. To re-cali-
