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.
