• • • • Important safety notice:
Components identified
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.
• • • • In case of AC rated voltage Capacitor, the part no. and
values will be indicated in the Schematic Diagram.
AC rated voltage capacitor:
C5700, C5701,C5703, C5704, C5705
