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-

18、ROMs, defined by ISO (International Organization for Standardization). 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 at an area called Lead-out. A Multi Session CD is a CD

19、 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. Fur

20、thermore, 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

21、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” ex

23、n. 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, various music discs encoded with copyright protection technologies are marketed

24、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 Session If the disc begins with a CD-DA session, it is recognized as a CD-DA (audio)

25、 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

26、analyzing of the disc. A disc with a mixed CD or CD-Extra format will be recognized as a CD-DA (audio) disc.

32、cal pick-up block may suffer electrostatic break-down because of the potential difference generated by the charged electrostatic load, etc. on clothing and the human body. During repair, pay attention to electrostatic break-down and also use the procedure in the printed matter which is included in t

33、he 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

34、 laser diode emission, observe from more than 30 cm away from the objective lens. 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 ma

35、rk 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.

36、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 viscou-s (sticky, less prone to flow) than ordinary solder so use ca

37、ution 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.
