15.1. Schematic Diagram Notes
(All schematic diagrams may be modified at any time with
the development of new technology)
Notes:
the development of new technology)
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.

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 Capacitors, the part no. and val-
ues will be indicated in the Schematic Diagram.
AC rated voltage capacitors:
C702, C710, C725, C727, C728
AC rated voltage capacitors:
C702, C710, C725, C727, C728
• 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.
