12 Schematic Diagram Notes
Notes:
·
Circuit voltage and waveform described herein shall be
regarded as reference information when probing defect
point, because it may differ from an actual measuring
value due to difference of Measuring instrument and its
measuring condition and product itself.
This schematic diagram may be modified at any time
with the development of new technology.

Important safety notice:
Components
identified
by
mark
have
special
characteristic s 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.
