· 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.
No mark : CD stop
( ) : CD play
· 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
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.
