• 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 without any symbol is ohm-type resis-
tor. 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 sym-
bol is microfarad. As to electrolytic capacitor, the expression
Ocapacitance/withstand voltageO 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 without prior notice.

• The indicated voltage in each section is the one measured by Digi-

tal Multimeter between such a section and the chassis with no sig-
nal 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 “
