- 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.

- Important safety notice:
Components identified by
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.
- 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.
Ground the soldering iron.
Put a conductive mat on the work table.
Do not touch the legs of IC or LSI with the fingers directly.
- Voltage and signal line
: Positive voltage line
: Negative voltage line
