CD-E67 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 • 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 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 " 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. REF.

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.
(

4. In the power section, a tape is being played back.
5. In the CD section, the CD is stopped.
