• Indicated voltage values are the standard values for the unit

measured by the DC electronic circuit tester (high-

impedance) with the chassis taken as standard. Therefore,

there may exist some errors in the voltage values,

depending on the internal impedance of the DC circuit

tester.

characteristics important for safety.

Furthermore, special parts which have purposes of fire-

retardant (resistors), high-quality sound (capacitors), low-

noise (resistors), etc. are used.

When replacing any of components, be sure to use only

manufacturer's specified parts shown in the parts list.

• The supply part number is described alone in the

replacement parts list.

Caution!

IC and LSI are sensitive to static electricity.

Secondary trouble can be prevented by taking care during

repair.

Cover the parts boxes made of plastics with aluminum foil.
