SAFETY-RELATED COMPONENT WARNING!! COMPONENTS IDENTIFIED BY MARK 0 OR DOTTED LINE WITH MARK 0 ON THE SCHEMATIC DIAGRAMS AND IN THE PARTS LIST ARE CRITICAL TO SAFE OPERATION. REPLACE THESE COMPONENTS WITH SONY PARTS WHOSE PART NUMBERS APPEAR AS SHOWN IN THIS MANUAL OR IN SUPPLEMENTS PUBLISHED BY SONY. CAUTION Use of controls or adjustments or performance of procedures other than those specified herein may result in hazardous radiation exposure. Flexible Circuit Board Repairing -Keep the temperature of the soldering iron around 270˚C during repairing. -Do not touch the soldering iron on the same conductor of the circuit board (within 3 times). -Be careful not to apply force on the conductor when soldering or unsoldering. Notes on Chip Component Replacement -Never reuse a disconnected chip component. -Notice that the minus side of a tantalum capacitor may be dam- aged by heat. NOTES ON HANDLING THE OPTICAL PICK-UP BLOCK OR BASE UNIT The laser diode in the optical pick-up block may suffer electrostatic breakdown because of the potential difference generated by the charged electrostatic load, etc. on clothing and the human body. During repair, pay attention to electrostatic breakdown and also use the procedure in the printed matter which is included in the repair parts. The flexible board is easily damaged and should be handled with care. NOTES ON LASER DIODE EMISSION CHECK The laser beam on this model is concentrated so as to be focused on the disc reflective surface by the objective lens in the optical pick- up block. Therefore, when checking the laser diode emission, observe from more than 30 cm away from the objective lens. SERVICE NOTE When the CD block is going to be inspected, be sure to connect beforehand the jig (J-2501-020-A) between the CD board (CNP706) and the DISPLAY board (CNP802). 2 General Speaker Woofer: 13 cm (5 1⁄8 inches) dia., Tweeter: 5 cm (2 inches) dia., 6 Ω, cone type (2) Inputs LINE IN jacks (2 phono jacks): Sensitivity 220 mV Outputs Headphones jack (stereo minijack): For 8 - 32 Ω impedance headphones Speaker terminals: For supplied 6 Ω impedance speaker Maximum power output 100 W Power requirements For personal component system: 230 V AC, 50 Hz For remote control: 3 V DC, 2 R6 (size AA) batteries Power consumption AC 110 W Dimensions Player: approx. 285 × 322 × 408 mm (w/h/d) (11 1⁄4 × 12 3⁄4 × 16 1⁄8 inches) Speaker: approx. 200 × 316 × 230 mm (w/h/d) (7 7⁄8 × 12 1⁄2 × 9 1⁄8 inches) Mass Player: approx. 7.7 kg (16 lb. 16 oz.)
