Ð 2 Ð Flexible Circuit Board Repairing ·Keep the temperature of the soldering iron around 270 ûC dur- ing 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. The laser diode in the optical pick-up block may suffer electro- static 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 HANDLING THE OPTICAL PICK- UP BLOCK OR BASE UNIT Laser Diode Properites ¥ Material: GaAlAs ¥ Wavelength: 780 nm ¥ Emission Duration: continuous ¥ Laser Output Power: less than 44.6 µW* * This output is the value measured at a distance of 200 mm from the objective lens surface on the 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. SAFETY-RELATED COMPONENT WARNING!! COMPONENTS IDENTIFIED BY MARK ! OR DOTTED LINE WITH MARK ! 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 PUB- LISHED BY SONY.ATTENTION AU COMPOSANT AYANT RAPPORT Ë LA SƒCURITƒ! LES COMPOSANTS IDENTIFIƒS PAR UNE MARQUE ! SUR LES DIAGRAMMES SCHƒMATIQUES ET LA LISTE DES PIéCES SONT CRITIQUES POUR LA SƒCURITƒ DE FONCTIONNEMENT. NE REMPLACER CES COM- POSANTS QUE PAR DES PIéCES SONY DONT LES NUMƒROS SONT DONNƒS DANS CE MANUEL OU DANS LES SUPPLƒMENTS PUBLIƒS PAR SONY.
