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 internalimpedance of the DC circuit tester.
No mark: Power ON
-
Important safety notice:
Components identified by
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 manufacture's
specified parts shown in the parts list.
Caution!
-
Secondary trouble can be prevented by taking care during repair.
-
IC and LSI are sensitive to static electricity.
-
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.
