17 Schematic Diagram
17.1. Schematic Diagram Notes
• This schematic diagram 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.
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:
C5700, C5701, C5702, C5704, C5705, C5706
AC rated voltage capacitors:
C5700, C5701, C5702, C5704, C5705, C5706
• 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.
•
*
REF is for indication only.
• Voltage and signal line
S6004:
Vol (-) switch.
S6006:
Vol (+) switch.
S6801:
Power switch (
).
S6804:
Open/Close switch ( OPEN/CLOSE).
