This schematic diagram may be modified at any time with the development of new technology.
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.
(resistors), etc. are used. When replacing any of components, be sure to use only manufacture´s specified parts shown in
theparts list.
Important safety notice:
There are special components used in this equipment which are important for safety.
These parts are marked by
in the schematic diagrams. It is essential that these critical parts should be replaced with
manufacturer’s specified parts to prevent shock, fire, or other hazards. Do not modify the original design without permission of
manufacturer.
manufacturer.
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.
