SECTION 7 DIAGRAMS 7-1. NOTE FOR PRINTED WIRING BOARDS AND SCHEMATIC DIAGRAMS (In addition to this, the necessary note is printed in each block) Note on Printed Wiring Board: • X : parts extracted from the component side. • Y : parts extracted from the conductor side. • x : parts mounted on the conductor side. • b : Pattern from the side which enables seeing. (The other layers' patterns are not indicated.) Caution: Pattern face side: (Side B) Parts face side: (Side A) 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. Q BCE Q These are omitted. BCE These are omitted. C Q These are omitted. BE Note on Schematic Diagram: • All capacitors are in µF unless otherwise noted. pF: µµF 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. • 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. • U : B+ Line. • V : B- Line. • H : adjustment for repair. • Voltages are taken with a VOM (Input impedance 10 MΩ). Voltage variations may be noted due to normal production tolerances. • Waveforms are taken with a oscilloscope. Voltage variations may be noted due to normal production tolerances. • Circled numbers refer to waveforms. • Signal path. E : TAPE PLAYBACK (DECK A) d : TAPE PLAYBACK (DECK B) G : RECORD J : CD PLAY (ANALOG OUT) c : CD PLAY (DIGITAL OUT) • Abbreviation AUS : Australian model CND : Canadian model JE : Tourist model KR : Korean model MY : Malaysia model SP : Singapore model TH : Thai model • Circuit Boards Location SENSOR 2 board SENSOR board CLAMP MOTOR board BD board PANEL board IN SW board INT/COUNT SW board LEAF SW board PANEL TC-B board PANEL TC-A board OUT SW board MAIN board CONNECTOR board LOAD MOTOR board AUDIO board 19 19
