@|ndicated 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.
Important safety notice:
Components identified byA\ 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.
