4. Press the function switch 2 [COMP.].

• <Normal case that the body is not magnetized>

The geomagnetic sensor mode screen is displayed. Each of 
X- and Y-outputs of the geomagnetic sensor, center coordi-
nates, and radius of the direction circle are displayed. For 
degeomagnetization, refer to 

P.54A-284

.

• <Case that the body is magnetized>

If the sensor value is outside the range between 450 and 
580, it is meant that the body is magnetized. The screen 
that calls upon to demagnetize the body stating "Demagne-
tize within range of acceptable level" is displayed. In this 
case, it is necessary to demagnetize the body and to cor-
rect the geomagnetic sensor. Refer to on-vehicle ser-
vice-vehicle magnetic compensation 

P.34-6

.

• When function switch 1 [CAL.COMP] is pressed at the pre-

vious screen, a message of urging rotation compensation is 
displayed. For the method of magnetization compensation 
by rotation, refer to 

P.54A-284

.

.

Release of service mode
The service mode is released by pressing the "DISP" switch 
[END] is pressed on the service mode first screen or the ser-
vice mode second screen, or by turning the ignition switch to 
the "LOCK" (OFF) position.
