@Indicated voltage values are the standard values for the unit measured by
the DC electronic circuit tester (high-impedance) with the chassis taken as
standard. Therefore, there may exist some errors in the voltage values,
depending on the internal impedance of the DC circuit tester.
@|mportant safety notice:
Components identified by", mark have special characteristics important
for safety. When replacing any of these components, use only
manufacturer’s specified parts.
*Caution!
IC and LSI are sensitive to static electricity.
Secondary trouble can be prevented by taking care furing 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.
