CD-E88 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.
