Confirmation of magnetization and
demagnetization

The RV meter automatically conducts geomagnetization cali-
bration by sampling direction data while the vehicle is normally
driving. The calibration can be done manually at any time.

.

1. Press function switch 3 for three seconds or more during the

environment information screen to call up the screen as
shown in the illustration.

2. When function switch 3 (CAL.COMP) is pressed, a message

of urging geomagnetization calibration is displayed.

3. Drive around the vehicle.

NOTE: When driving around the vehicle to correct the sen-
sor, select a safe and open area where there are no struc-
tures exist such as the high-tension line and the iron bridge
that affect the geomagnetic sensor in circumference.

4. A message of completing geomagnetization calibration is

displayed.

• When pressing "DISP" and "ADJ" switches

• When pressing function switch 3 (CANCEL)

• When operating auto A/C and audio

• When turning the ignition switch to the "OFF" (LOCK) posi-

tion

Demagnetization and correction method

1. Demagnetize the body using a commercial demagnetizer.

2. While keeping the distance between the tip of demagnetizer

and the roof panel to approximately 5 cm (2.0 inches), move
the demagnetizer slowly with a sweeping manner on the
rear-half surface of roof panel.

CAUTION

If the tip of demagnetizer touches the roof panel, the mag-
netizing condition of body becomes worse to the contrary.
Absolutely avoid this.
3. Slowly draw the demagnetizer apart from the body. Turn

OFF the switch of demagnetizer when it is apart from the
body more than 5 cm.

CAUTION

If the demagnetizer is turned OFF near the body or it is
suddenly separated from the body, the magnetizing condi-
tion of body becomes worse to the contrary. Absolutely
avoid these.
4. After degeomagnetization, geomagnetization calibration is

carried out.
