some errors in the voltage values, depending on theinternal
impedance of the DC circuit tester.

- 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
manufacturer´s specified parts shown in the parts list.
- The supply part number is described alone in the replacement
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.
- Voltage and signal line
: Positive voltage line
: Negative voltage line
