Compass: Testing and Inspection
PRE-CHECK
1. SELECTING COMPASS DISPLAY MODE
a. The Comp switch allows you to select the Display or Non-display mode of the compass.
2. SETTING ZONE
a. Deviation between the "magnetic north" and "actual north" differs depending on the location. Therefore, adjustment of the magnetism is
required. Since the magnetic condition differs according to the area where the vehicle is used, it is necessary for each user to set the zone (refer
to "Compass Zone Map"). The zone setting can be changed using the Comp switch of the inner mirror.
3. PERFORMING CALIBRATION
a. Because each vehicle has its own magnetic field, calibration should be performed for each vehicle. This compass function is used when storing
the record of the vehicle's magnetic field.
4. WHEN COMPASS MAGNETIZED:
a. A compass could be magnetized during shipping by vessels or freight cars. Before delivery, make sure to perform calibration and ensure that
calibration is done properly. If calibration cannot be completed despite driving the vehicle in a circle several times, the vehicle's magnetic field
may be interfering with the calibration. Demagnetize the vehicle using a demagnetizer and perform calibration again.
