- 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.
No mark: MD STOP

Important safety notice:
Components identified by mark have special characteristics important for safety.
Furthermore, special parts which have purpose of fire-retardant (resistors), high-quality sound
(capacitors), low-noise (resistors), etc. are used. When replacing any of components, be sure to
use only manufacture's specified parts shown in theparts 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.
