Precautions

1) Be sure to apply a screw securing torque when attaching a

part.
The securing torque should be 0.04 N-m (0.4 kgf-cm) unless
otherwise specified.

2) Always unplug the power cord of the set before attaching,

removing or soldering a part.

3) When unplugging a connector, do not pull the wire but grasp

the connector body.

4) Do not make an adjustment or rotate a potentiometer blindly

while the source of trouble is not identified.

5) Before adjusting electrical circuitry, be sure to wait for more

than 10 minutes after turning the power on.
