15.2. Schematic Diagram Notes
This schematic diagram may be modified at any time with the development of new technology.
Important safety notice:
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 (resis-
tors), etc. are used. When replacing any of components, be sure to use only manufacture's specified parts shown in the parts
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 manu-
facturer’s specified parts to prevent shock, fire, or other hazards. Do not modify the original design without permission of man-
ufacturer.

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.
