• Importance 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, C5706 & C5707
• Resistor
Unit of resistance is OHM [Ω] (K=1,000).
• Capacitor
Unit of resistance is µF, unless otherwise noted. F=Farad,
pF=Pico-Farad
• Coil
Unit of inductance is H, unless otherwise noted.
