• 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 Digital Multimeter between such a section and the chas-
sis with no signal given.
1. In the tuner section,
( ) indicates AM/FM stereo
2. In the CD section, the CD is stopped.
• Parts marked with “ 1 ” ( ) 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 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
