Compass Calibration
This is a Fast Auto-Cal compass that manually enters the calibration mode when the US/M and Step buttons are pressed for more than 6 seconds
in the Compass/Temperature screen. The 'CAL' will illuminate to indicate the compass is in calibration mode. Drive the vehicle around in all four
compass directions, such as driving around a street block several times or driving in 2-3 circles with a slow to medium speed. When the calibration
process is completed, the 'CAL' will go OFF and the compass will function normally. The calibration should take place in an area that is leveled
and minimum of 50 feet away from metal objects, power lines, buildings and large steel structures.
If the 'CAL' message remains in the display, either there is excessive magnetism near the compass, or the unit is faulty. If the wrong direction is
still indicated in the compass display, the area selected for calibration may be too close to a strong magnetic field. If the compass cannot be
calibrated, further diagnosis is necessary.
Compass Variance
Compass Variance is the difference between Magnetic North and Geographic North. In some areas of the country, the difference between
Magnetic and Geographic North is great enough to cause the compass to give false readings. If this occurs, the compass variance must be set.
To set the variance: Turn the ignition ON and set display to Comp./Temp. Simultaneously press both the US/M and STEP button for 0.1 to 2
seconds. The VAR indicator will light up and the current zone number will be displayed. Press STEP button to select the proper variance zone as
shown on the map. After 5 seconds of inactivity, the displayed zone will be automatically set, and normal operation will resume.
