2 CDX-MP30 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. 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. This label is located on the bottom of the chassis. This label is located on the drive units internal chassis. optical pick-up bloc k semi-fixed resistor SERVICE NOTES If the optical pick-up block is defective, please replace the whole optical pick-up block. Never turn the semi-fixed resistor located at the side of optical pick-up block. CAUTION Use of controls or adjustments or performance of procedures other than those specified herein may result in hazardous radiation exposure. TEST DISCS This set can playback CD-R and CD-ROM discs. The following test discs should be used to check the capability: CD-R test disc TCD-R082LMT (Part No. J-2501-063-1) CD-RW test disc TCD-W082L (Part No. J-2501-063-2) NOTES ON CD-R/CD-RW DISCS -You can play CD-Rs (recordable CDs)/CD-RWs (rewritable CDs) designed for audio use on this unit. Look for these marks to distinguish CD-Rs/CD-RWs for audio use. These marks denote that a disc is not for audio use. -Some CD-Rs/CD-RWs (depending on the equipment used for its recording or the condition of the disc) may not play on this unit. -You cannot play a CD-R/CD-RW that is not finalized-ˆ— . -ˆ—A process necessary for a recorded CD-R/CD-RW disc to be played on the audio CD player. 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.
