0 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

I- important saiety notice:
Components identified by A; 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 manufacturers specified parts show in the parts list.

- Caution!
IO and LS] are sensitive to static electricity.
Secondary trouble can be prevented by taking care during repair.
Cover the parts boxes made of plastics with aluminum toil.
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.
