Notice that the minus side of a tantalum capacitor may bedamaged by heat.Flexible Circuit Board Repairing Keep the temperature of the soldering iron around 270 Cduring 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.CAUTIONUse of controls or adjustments or performance of proceduresother than those specified herein may result in hazardous radiationexposure.SAFETY-RELATED COMPONENT WARNING!COMPONENTS IDENTIFIED BY MARK 0 OR DOTTED LINEWITH MARK 0 ON THE SCHEMATIC DIAGRAMS AND INTHE PARTS LIST ARE CRITICAL TO SAFE OPERATION.REPLACE THESE COMPONENTS WITH SONY PARTS WHOSEPART NUMBERS APPEAR AS SHOWN IN THIS MANUAL ORIN SUPPLEMENTS PUBLISHED BY SONY.This appliance is classified asa CLASS 1 LASER product.The CLASS 1 LASERPRODUCT MARKING islocated on the rear exterior.Power consumptionnd CX-J3000M (CX-J3000M (CX-J3000M (Russian model):70 wattsMexican model):90 wattsChilean and Peruvian models):100 wattsCX-J3000 aDimensions (w/h/d) incl. projecting parts and controlsAmplifier/Tuner/Tape/CD section:Approx. 270 300 294 mmMassCX-J3000 and CX-J3000M (Russian model):Approx. 4.8 kgCX-J3000M (Mexican, Chilean and Peruvian models) Approx. 5.5 kgDesign and specifications are subject to change without notice.RadioFans.CN 收音机爱 好者资料库3CX-J3000/J3000MYou can play back the following discs on this system. Other discs cannot be played back.List of playable discs* CX-J3000M onlyPlayable discsFormat of discsDisc logoAudio CDsCD-R/CD-RW (audio data/MP3 files*)Discs that this system cannotplay CD-ROMsCD-Rs/CD-RWs other than those recorded in the following formats: music CD format MP3 format that conforms to ISO96601) Level 1/Level 2, Joliet, Romeo or Multi Session2) Discs with non-standard shapes (e.g., heart, square, star) cannot be played on this unit. Attempting to do so may damage the unit. Do not use such discs. A disc with paper or stickers on it. A disc that has the adhesive, cellophane tape, or a sticker still left on it.1)A logical format of files and folders on a CD-ROMs, defined by ISO (International Organization for Standardization).2)Multi SessionThis is a recording method that enables adding of data using the Track-At-Once method. Conventional CDs begin at a CD control area called the Lead-in and end at an area called Lead-out. A Multi Session CD is a CD having multiple sessions, with each segment from Lead-in to Lead-out regarded as a single session.Notes on CD-R and CD-RW Some CD-Rs or CD-RWs cannot be played on this system depending upon the recording quality or physical condition of the disc, or the characteristics of the recording device. Furthermore, the disc will not play if it has not been correctly finalized. For more information, see the operating instructions for the recording device. Discs recorded on CD-R/CD-RW drives may not be played back because of scratches, dirt, recording condition or the drivers characteristics. CD-R and CD-RW discs recorded in packet write format are not supported. CD-R and CD-RW discs that have not ended by “closing the session” are not supported. The system may be unable to play MP3 format files that do not have the “.MP3” extension. Attempting to play non-MP3 format files that have the “.MP3” extension may result in noise or malfunction. With formats other than ISO9660 Level 1, Joliet and Romeo, folder names or file names may not be displayed correctly. The following discs take a longer time to start playback. a disc recorded with complicated tree structure. a disc recorded in Multi Session. a disc to which data can be added (non-finalized disc).Music discs encoded withcopyright protection technologiesThis 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 do not conform to the CD standard and may not be playable by this product.Cautions when playing a discthat is recorded in MultiSession If the disc begins with a CD-DA session, it is recognized as a CD-DA (audio) disc, and playback continues until an MP3 session is encountered. If the disc begins with an MP3 session, it is recognized as an MP3 disc, and playback continues until a CD-DA (audio) session is encountered. The playback range of an MP3 disc is determined by the tree structure of files produced by analyzing of the disc. A disc with a mixed CD or CD-Extra format will be recognized as a CD-DA (audio) disc.RadioFans.CN 收音机爱 好者资料库4CX-J3000/J3000MTABLE OF CONTENTS1.SERVICING NOTES. 52.GENERAL. 63.DISASSEMBLY3-1.DISASSEMBLY FLOW . 83-2.SIDE PANEL (L/R). 83-3.TOP PANEL SECTION . 93-4.OPTICAL BLOCK SECTION. 93-5.OPTICAL PICK-UP (KSS-213R). 103-6.FRONT PANEL SECTION. 103-7.MECHANICAL DECK (CWM43FR55) . 113-8.MAIN BOARD . 114.TEST MODE. 125.MECHANICAL ADJUSTMENTS. 136.ELECTRICAL ADJUSTMENTS. 137.DIAGRAMS7-1.BLOCK DIAGRAM SERVO SECTION . 177-2.BLOCK DIAGRAM TUNER SECTION . 187-3.BLOCK DIAGRAM AUDIO SECTION . 197-4.BLOCK DIAGRAM DISPLAY/POWER SUPPLY SECTION . 207-5.PRINTED WIRING BOARD CD SECTION (J3000) . 227-6.SCHEMATIC DIAGRAM CD SECTION (J3000) . 237-7.PRINTED WIRING BOARD CD/MP3 SECTION (SIDE A) (J3000M) . 247-8.PRINTED WIRING BOARD CD/MP3 SECTION (SIDE B) (J3000M) . 257-9.SCHEMATIC DIAGRAM CD/MP3 SECTION (J3000M) . 267-10.

Therefore, when checking the laser diode emission,observe from more than 30 cm away from the objective lens.UNLEADED SOLDERBoards 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 withthe lead free mark due to their particular size): LEAD FREE MARKUnleaded solder has the following characteristics. Unleaded solder melts at a temperature about 40 C higherthan ordinary solder.Ordinary soldering irons can be used but the iron tip has to beapplied to the solder joint for a slightly longer time.Soldering irons using a temperature regulator should be set toabout 350 C.Caution: The printed pattern (copper foil) may peel away ifthe heated tip is applied for too long, so be careful! Strong viscosityUnleaded solder is more viscou-s (sticky, less prone to flow)than ordinary solder so use caution not to let solder bridgesoccur such as on IC pins, etc. Usable with ordinary solderIt is best to use only unleaded solder but unleaded solder mayalso be added to ordinary solder.
