9、 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. Flexible Circ

10、uit Board Repairing Keep the temperature of the soldering iron around 270C 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

11、Never reuse a disconnected chip component. Notice that the minus side of a tantalum capacitor may be dam- aged by heat. 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

12、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 40C higher than ordinary solder. Ordinary soldering irons can be used but the iron tip has to be applied to the sol

13、der joint for a slightly longer time. Soldering irons using a temperature regulator should be set to about 350C. 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

14、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. CAUTION Use of controls or adjustments or performance of procedures other th

15、an those specified herein may result in hazardous radiation exposure. On AC power adaptor Use only the AC power adaptor supplied. If your CD player is not supplied with the one, use the AC-E45HG AC power adaptor. Do not use any other AC power adaptor. It may cause a malfunction. Polarity of the plug

16、 Do not touch the AC power adaptor with wet hands. Connect the AC power adaptor to an easily accessible AC outlet. Should you notice an abnormality in the AC power adaptor, disconnect it from the AC outlet immediately. ATTENTION AU COMPOSANT AYANT RAPPORT LA SCURIT! LES COMPOSANTS IDENTIFS PAR UNE M

18、following 3 music sources on this CD player: Audio CDs (CDDA format) CDs with ATRAC3plus/ATRAC3 format files (ATRAC CD) CDs with MP3 format files (MP3 CD) Usable disc formats You can use ISO 9660 Level 1/2 and Joliet extension format discs only. About CD-Rs/RWs This CD player can play CD-Rs/RWs reco

19、rded in the ATRAC3plus/ATRAC3, MP3 or CDDA* format, but playback capability may vary depending on the quality of the disc and the condition of the recording device. * CDDA is the abbreviation for Compact Disc Digital Audio. It is a recording standard used for the Audio CDs. Music discs encoded with

20、copyright protection technologies This product is designed to playback discs that conform to the Compact Disc (CD) standard. Recently, various music discs encoded with copyright protection technologies are marketed by some record companies. Please be aware that among those discs, there are some that

21、 do not conform to the CD standard and may not be playable by this product. Notes This CD player cannot record music content on recordable media, such as CD-Rs/RWs. CD-Rs/RWs recorded in the ATRAC3plus/ATRAC3 format cannot be played on your computer. RadioFans.CN 收音机爱 好者资料库 3 XP-ZV610/ZV616 TABLE OF

25、LIST.36 RadioFans.CN 收音机爱 好者资料库 4 XP-ZV610/ZV616 SECTION 1 SERVICING NOTE 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

26、 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 r

27、eflective 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. BEFORE REPLACING THE OPTICAL PICK-UP BLOCK Please be sure to check thoroughly the parameters as par the “Optical Pick-U

28、p Block Checking Procedures” (Part No.: 9-960-027-11) issued separately before replacing the optical pick-up block. FOK output: IC601 yg pin When checking FOK, remove the lead wire to disc motor. RF signal P-to-P value: 0.45 to 0.65 Vp-p LASER DIODE AND FOCUS SEARCH OPERATION CHECK During normal ope

29、ration of the equipment, emission of the laser diode is prohibited unless the upper lid is closed while turning ON the S820. (push switch type) The following checking method for the laser diode is operable. Method: Emission of the laser diode is visually checked. 1. Open the upper lid. 2. With a dis

30、c not set, turn on the S820 with a screwdriver having a thin tip as shown in Fig.1. 3. Press the u/ENT button. 4. Observing the objective lens, check that the laser diode emits light. When the laser diode does not emit light, automatic power control circuit or optical pickup is faulty. In this opera

31、tion, the objective lens will move up and down 4 times along with inward motion for the focus search.
