• Note for Printed Wiring Boards and Schematic Diagrams Note on Printed Wiring Board: • X : parts extracted from the component side. • Y : parts extracted from the conductor side. • f : internal component. • : Pattern from the side which enables seeing. (The other layers' patterns are not indicated.) Caution: Pattern face side: (Conductor Side) Parts face side: (Component Side) Parts on the pattern face side seen from the pattern face are indicated. Parts on the parts face side seen from the parts face are indicated. • Indication of transistor C Q These are omitted. BE Q BCE These are omitted. Q BCE These are omitted. Note on Schematic Diagram: • All capacitors are in µF unless otherwise noted. (p: pF) 50 WV or less are not indicated except for electrolytics and tantalums. • All resistors are in Ω and 1/4 W or less unless otherwise specified. • f : internal component. • 2 : nonflammable resistor. • 5 : fusible resistor. • C : panel designation. Note: The components identified by mark 0 or dotted line with mark 0 are critical for safety. Replace only with part number specified. Note: Les composants identifiés par une marque 0 sont critiques pour la sécurité. Ne les remplacer que par une pièce portant le numéro spécifié. • A : B+ Line. • B : B- Line. • Voltages and waveforms are dc with respect to ground under no-signal conditions. - CD Board - no mark : CD PLAY - Other Section - no mark : TUNER ( ) : CD PLAY TAPE PLAY { } : REC • Voltages are taken with a VOM (Input impedance 10 MΩ). Voltage variations may be noted due to normal produc- tion tolerances. • Waveforms are taken with a oscilloscope. Voltage variations may be noted due to normal produc- tion tolerances. • Circled numbers refer to waveforms. • Signal path.
