3.7.1. REPLACING VOLUME
If the steering operability becomes poor, and adjusting the VOLUME SETTING in the TEST MODE is
ineffective, the cause may be the failure of the Volume Gear to mesh and/or the Volume Potentiometer
malfunctioning.
When the Steering Wheel is rotated fully left or right, if the Volume shaft is rotating within the movable
range, the Volume is unlikely to be damaged. Use the procedure described herein to position the steering
VR such that the correct centre value (refer to Section 5.3.5) is displayed when the Steering Wheel is at
rest.
1. Power OFF the machine and
remove the IEC lead from the
wall outlet.
2. Remove the three
tamperproof screws and open
the Control Panel.
