Compass: Adjustments

Zone Variation Change Procedure




The difference between magnetic North and geographical North can sometimes be great enough to cause false compass readings. This difference is known as variance. In order for the compass to operate properly (accurately) in a particular zone, the zone variation must be calibrated using the procedure given in the figure.




CALIBRATION FUNCTION OF COMPASS
The direction display is equipped with a calibration feature. If vehicle direction is not shown correctly, carry out initial correction.
1. Pushing the COMPASS switch for about 10 seconds will enter the initial calibration mode.
2. Drive the vehicle slowly in a circle, in an open, safe place. The initial calibration is completed in about three turns.

NOTE: In places where the terrestrial magnetism is extremely disturbed, the initial correction may start automatically.
