- Important safety notice : / Components identified by 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 shown in the parts 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.
