Notes On Schematic Diagram
•Resistor:
To differentiate the units of resistors, such symbol as K
and M are used: the symbol K means 1000 ohm and
the symbol M means 1000 kohm and the resistor with-
out any symbol is ohm-type resistor. Besides, the one
with “Fusible” is a fuse type.
• Capacitor:
To indicate the unit of capacitor, a symbol P is used:
this symbol P means pico-farad and the unit of the
capacitor without such a symbol is microfarad. As to
electrolytic capacitor, the expression “capacitance/
withstand voltage” is used.
(CH), (TH), (RH), (UJ): Temperature compensation
(ML): Mylar type
(P.P.): Polypropylene type
• Schematic diagram and Wiring Side of P.W.Board for
this model are subject to change for improvement with-
out prior notice.
• The indicated voltage in each section is the one mea-
sured by Digital Multimeter between such a section
and the chassis with no signal given.
1. In the tuner section,
indicates AM
indicates FM stereo
2. In the main section, a tape is being played back.
3. In the deck section, a tape is being played back.
( ) indicates the record state.
4. In the power section, a tape is being played back.
5. In the CD section, the CD is stopped.
• Parts marked with “ “ ( ) are important
for maintaining the safety of the set. Be sure to replace
these parts with specified ones for maintaining the
safety and performance of the set.
