12、onnected chip component. Notice that the minus side of a tantalum capacitor may be damaged by heat. Flexible Circuit Board Repairing Keep the temperature of the soldering iron around 270 C during repairing. Do not touch the soldering iron on the same conductor of the circuit board (within 3 times).

13、Be careful not to apply force on the conductor when soldering or unsoldering. CAUTION Use of controls or adjustments or performance of procedures other than those specified herein may result in hazardous radiation exposure. UNLEADED SOLDER Boards requiring use of unleaded solder are printed with the

14、 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

15、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 appl

16、ied for too long, so be careful! Strong viscosity Unleaded solder is more viscou-s (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

17、 be added to ordinary solder. 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.

18、SUPPLEMENTS PUBLISHED BY SONY. RadioFans.CN 收音机爱 好者资料库 CX-BK33 3 You can play back the following discs on this system. Other discs cannot be played back. List of playable discs Discs that this system cannot play An 8 cm disc An 8 cm disc converted to a standard disc using an adaptor CD-ROMs CD-Rs/CD

19、-RWs other than those recorded in the following formats: music CD format MP3 format that conforms to ISO96601) Level 1/Level 2, Joliet or Multi Session2) A disc that has a non-standard shape (e.g., card, heart). A disc with paper or stickers on it. A disc that has the adhesive, cellophane tape, or a

20、 sticker still left on it. 1) ISO9660 Format The most common international standard for the logical format of files and folders on a CD-ROM. There are several specification levels. In Level 1, file names must be in the 8.3 format (no more than eight characters in the name, no more than three charact

21、ers in the extension “.MP3”) and in capital letters. Folder names can be no longer than eight characters. There can be no more than eight nested folder levels. Level 2 specifications allow file names and folder names up to 31 characters long. Each folder can have up to 8 trees. For Joliet in the exp

22、ansion format (file and folder names can have up to 32 characters), make sure of the contents of the writing software, etc. 2) Multi Session This 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 a

23、t 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. Playable discs Format of discsDisc logo Audio CDs CD-R/CD-RW (audio data/MP3 files) Notes on CD-R and CD-RW Some CD-Rs or CD-RWs cannot be played o

24、n 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 recor

25、ded 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 multi- session that have not ended by “closing the session” are not supported. The system may be unable to play MP3 format files that do no

26、t 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 and 2, folder names or file names may not be displayed correctly. The following discs take a longer time to start playback.

27、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 with copyright protection technologies This product is designed to playback discs that conform to the Compact Disc (CD) standard. Recently,

28、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 disc that is recorded in Multi Sess

29、ion If the disc begins with a CD-DA session, it is recognized as a CD-DA (audio) disc, and only the first session will be played back. 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 a

30、n MP3 disc is determined by the tree structure of files produced by analyzing of the disc. A disc with a mixed CD format will be recognized as a CD-DA (audio) disc. Data part of CD-Extras1) Audio part of Mixed CDs2) 1) CD-Extra: This format records audio (audio CD data) on the tracks in session 1 an

31、d data on the tracks in session 2. 2) Mixed CD: This format records data on the first track and audio (audio CD data) on the second and subsequent tracks of a session.
