2 CFD-G550CP 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 proce- dures other than those specified herein may result in haz- ardous 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. -Abbreviation E41 : AC 230V area in E model MX : Mexican model Power requirements For CD radio cassette-corder: MX model: 120 V AC, 60 Hz E41 model: 230 V AC, 50 Hz 12 V DC, 8 size D (R20) batteries For remote control: 3 V DC, 2 size AAA (R03) batteries Power consumption AC 30 W Battery life For CD radio cassette-corder:FM recordingSony R20P: approx. 6 hSony alkaline LR20: approx. 18 hTape playbackSony R20P: approx. 1.5 hSony alkaline LR20: approx. 6 hCD playbackSony R20P: approx. 1 hSony alkaline LR20: approx. 4 h Dimensions Approx. 530 × 327 × 241 mm (w/h/d) (incl. projecting parts) Mass Approx. 8 kg (incl. batteries) Supplied accessories AC power cord (1) Remote control (1) Design and specifications are subject to change without notice.

3 CFD-G550CP - UNLEADED SOLDER Boards requiring use of unleaded solder are printed with the lead- free mark (LF) indicating the solder contains no lead. (Caution: Some printed circuit boards may not come printed with the lead free mark due to their particular size.) : LEAD FREE MARK Unleaded solder has the following characteristics. -Unleaded solder melts at a temperature about 40°C higher than ordinary solder. Ordinary soldering irons can be used but the iron tip has to be applied to the solder joint for a slightly longer time. Soldering irons using a temperature regulator should be set to about 350°C. Caution: The printed pattern (copper foil) may peel away if the heated tip is applied for too long, so be careful! -Strong viscosity Unleaded solder is more viscous (sticky, less prone to flow) than ordinary solder so use caution not to let solder bridges occur such as on IC pins, etc. -Usable with ordinary solder It is best to use only unleaded solder but unleaded solder may also be added to ordinary solder.
