MDS-JE320 6-2. CIRCUIT BOARDS LOCATION SW board DISPLAY board BD board EJECT SW board CONTROL (SW) board - 25 - MAIN board THIS NOTE IS COMMON FOR PRINTED WIRING BOARDS AND SCHEMATIC DIAGRAMS. (In addition to this necessary note is printed in each block.) For schematic diagrams. Note: • 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. • % : indicates tolerance. • ¢ : internal component. • 2 : nonflammable resistor. • 1 : fusible resistor. • C : panel designation. Note: The components identified by mark ! or dotted line with mark ! are critical for safety. Replace only with part number specified. Note: Les composants identifiés par une marque ! sont critiques pour la sécurité. Ne les remplacer que par une pièce portant le numéro spécifié. • Waveform • BD SECTION 1 IC101 1,2 I, J (PLAY mode) • MAIN SECTION 1 IC316 @¶ (XOUT) 0.46Vp-p 2 IC101 4 A (PLAY mode) 11.998MHz 3.2Vp-p 2 IC316 @¢ (XOUT-T) 0.1Vp-p 32.77kHz 2.6Vp-p 3 IC101 8,9 E, F (PLAY mode) 3 IC307 0 (LRCK1), @• (LRCK2) • U : B+ Line. • V : B- Line. • H : adjustment for repair. • Voltages and waveforms are dc with respect to ground under no-signal (detuned) conditions.
