Therefore, when checking the laser diode emis-sion, observe from more than 30 cm away from the objective lens.When replacing the main chassis assy of mechanism deck whichhave the “CAUTION LABEL” attached, please be sure to put anew CAUTION LABEL (3-223-913-11) to the main chassis assy. SAFETY-RELATED COMPONENT WARNING!COMPONENTS IDENTIFIED BY MARK 0 OR DOTTEDLINE WITH MARK 0 ON THE SCHEMATIC DIAGRAMSAND IN THE PARTS LIST ARE CRITICAL TO SAFEOPERATION. REPLACE THESE COMPONENTS WITHSONY PARTS WHOSE PART NUMBERS APPEAR ASSHOWN IN THIS MANUAL OR IN SUPPLEMENTS PUB-LISHED BY SONY.SERVICING NOTESNOTES ON HANDLING THE OPTICAL PICK-UP BLOCK OR BASE UNITTEST DISCThis set can playback a CD-R, CD-RW for audio use. When testthis set, use the following test disc.Test disc for CD-R: TCD-R082LMT (Part No.: J-2502-063-1)Test disc for CD-RW: TCD-W082L (Part No.: J-2502-063-2)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.Flexible Circuit Board Repairing Keep the temperature of the soldering iron around 270 C dur-ing repairing. Do not touch the soldering iron on the same conductor of thecircuit board (within 3 times). Be careful not to apply force on the conductor when solderingor unsoldering.RadioFans.CN 收音机爱 好者资料库33M5F-18C821SECTION 1DISASSEMBLY This set can be disassembled in the order shown
