Find the vehicle's currentlocation and variance zonenumber on the map.Zones 1 through 15 areavailable.3. Press V to scroll through andselect the appropriatevariance zone.4. Press 3 until the vehicleheading, for example, N forNorth, is displayed in the DIC.5. Calibrate the compass. See“Compass CalibrationProcedure” following.Compass CalibrationThe compass can be manuallycalibrated. Only calibrate thecompass in a magnetically cleanand safe location, such as an openparking lot, where driving thevehicle in circles is not a danger.Also calibrate the compass, awayfrom tall buildings, utility wires,manhole covers, or other industrialstructures, if possible.If the DIC display does not show aheading, for example, N for North,or the heading does not changeafter making turns, there may be astrong magnetic field interfering withthe compass. Interference may becaused by a magnetic antennamount, magnetic note pad holder,or any other magnetic item. Turn offthe vehicle, move the magneticitem, then turn on the vehicle andcalibrate the compass.Compass Calibration Procedure1.
