- 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 theinternal
impedance of the DC circuit tester.

- Important safety notice:
Components identified by mark have special 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
