10 - 2 VOLUME ADJUSTMENT/REPLACEMENT
In case the operability of the right and left levers are poor, and the performed CALIBRA-
TION in test mode does not improve the situation, the cause may be failure of the Volume
Gear’s engagement in the ASSY LEVER MECHA inside the control panel and or Volume
malfunctioning. Follow the following procedure to perform Volume adjustment or re-
placement. Since work is performed inside the energized cabinet, be very careful not to
touch undesigned places.
