Calibration Procedure for Compass=NBEL0155The difference between magnetic North and geographical North
can sometimes be great enough to cause false compass readings.
In order for the compass to operate accurately in a particular zone,
it must be calibrated using the following procedure.
SEL738UA
SEL065V
CORRECTION FUNCTIONS OF COMPASSNBEL0155S01The direction display is equipped with automatic correction func-
tion. If the direction is not shown correctly, carry out initial correc-
tion.
INITIAL CORRECTION PROCEDURE FOR COMPASSNBEL0155S021. Pushing the ªModeº switch for about 10 seconds will enter the
initial correction mode. The direction bar starts blinking.
2. Turn the vehicle slowly in an open, safe place. The initial cor-
rection is completed in one or two turns.
NOTE:
In places where the terrestrial magnetism is extremely disturbed,
the initial correction may start automatically.
