2 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. 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, ob- serve 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. SERVICE NOTES This label is located on the bottom of the chassis. This label is located on the drive units internal chassis. When replacing the chassis (T.U) of mechanism deck which have the CAUTION LABEL attached, please be sure to put a new LABEL (OP CAUTION) (3-223-913-01) to the chassis (T.U). CDX-L380X CLASS 1 LASER PRODUCT VIEW DIRECTLY WITH OPTICAL INSTRUMENTSDO NOT STARE INTO BEAM OR INVISIBLE LASER RADIATION WHEN OPEN CAUTION 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-2502-063-1) CD-RW test disc TCD-W082L (Part No. J-2502-063-2) 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/a 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.

3 EXTENSION CABLE AND SERVICE POSITION When repairing or servicing this set, connect the jig (extension cable) as shown below. -Connect the MAIN board (CNP301) and the SERVO board (CN1) with the extension cable (Part No. J-2502-011-1). CDX-L380X - 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.
