13.1. Schematic Diagram Notes
(All schematic diagrams may be modified at any time with
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.
• In case of AC rated voltage Capacitors, the part no. and val-
ues will be indicated in the Schematic Diagram.
AC rated voltage capacitors:
C1702, C1710, C1725, C1727, C1728
•
Resistor
Unit of resistance is OHM [
Ω
] (K=1,000, M=1,000,000).
•
Capacitor
Unit of capacitance is
μ
F, unless otherwise noted. F=Farads,
pF=pico-Farad.
•
Coil
Unit of inductance is H, unless otherwise noted.
