stepped on. Check Volume values in the TEST mode. Since work is performed inside the
energized cabinet, be very careful so as not to touch undesignated places. Touching places not
specified can cause electric shock or short circuit.
Loosen 2 screws which secure the Volume Bracket to adjust the gear mesh.
Tighten the 2 screws.
In the TEST mode, check to ensure that the Volume Values are within the appropriate range and
vary smoothly in consistency with the Pedal operation.
