 The indicated voltage in each section is the one measured

by Digital Multimeter between such a section and the chas-
sis 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.

•

 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 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 micro-micro-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
