NOTES ON SCHEMATIC DIAGRAM
� Resistor: To differentiate the units of resistors, the 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 an ohm resistor. The resistor designated "Fusible" is a fase type resistor. � 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 � The indicated voltage in each section is the one measured by Digital Multimeter between such a section and the chassis with no signal given. 1. Tuner: ( ): AM mode Marking except for ( ): FM mode 2. CD ( ): Play mode Marking except for ( ): Stop state 3. Deck section ( ): Record mode Marking except for ( ): Playback mode Display / Control section: ( ): Active state Marking except for ( ): CD Function mode at stop state � Schematic Diagram and Wiring Side of P.W.Board for this model are subject to change for improvement without prior notice. � 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.
