• 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.
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 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

model are subject to change for improvement without prior
notice.
