Compass Zone
The zone is set to zone eight upon

is not set correctly.
Compass variance is the difference
between the earth's magnetic north
and true geographic north. If the
compass is not set to the zone

give false readings. The compass
must be set to the variance zone in
which the vehicle is traveling.
