with the chassis taken as standard. Therefore, there may exist
some errors in the voltage values, depending on
theinternalimpedanceof the DC circuit tester.

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 shownintheparts 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.
