® NOTES ON SCHEMATIC DIAGRAM
- Resistor: 1. Tuner
To differentiate the units of resistors, the symbol as K and M ( ): AM mode
are used: the symbol K means 1000 ohm and the symbol M Marking except for ( ): FM mode
means 1000 kohm and the resistor without any symbol is an 2. CD
ohm resistor. The resistor designated Fusible is a fuse type ( ): Play mode

resistor

' Capacitor:
To indicate the unit of capacitor, a symbol P is used: this
symbol P means micro-micrO-farad and the unit ofthe capacitor
without such a sym bol is microfarad. As to electrolytic capacitor,
the expression "capacitance/withstand voltage is used.
(CH), (TH), (FlH), (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.

Marking except for ( ): Stop state
3. Deck section
( )1 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 A (I: : :l) 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.
