Notes:
• Important safety notice:
Components identified by
mark have special characteris-
tics important for safety.
Furthermore, special parts which have purposes of fire-retar-
dant (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.

• Resistor
Unit of resistance is OHM [
Ω] (K=1,000, M=1,000,000).
• Capacitor
Unit of capacitance is
μF, unless otherwise noted. F=Farads,
pF=pico-Farad.
• Coil
Unit of inductance is H, unless otherwise noted.
