[1] Notes On Schematic Diagram
[2] Types Of Transistor And LED
•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
"capacitance/withstand voltage is used".
(CH), (TH), (RH), (UJ): Temperature compensation
(ML): Mylar type
(P.P.): Polypropylene

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 CD section, the CD is stopped.
Parts marked with “ ( ) are important for main-
taining the safety of the set. Be sure to replace these parts with
specified ones for maintaining the safety and performance of the
set.
