13、ead. (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 use

14、d 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 Unleade

15、d solder is more viscou-s (sticky, less prone to flow) than ordinary solder so use caution not to let solder bridges oc- cur 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.

Audio tracks in MP3PRO format. A disc that has a non-standard shape (e.g., card, heart). A disc with paper or

25、stickers on it. A disc that has the adhesive, cellophane tape, or a sticker still left on it. *1ISO9660 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

26、more than eight characters in the name, no more than three characters in the extension “.MP3” or “.JPG”) 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 3

27、1 characters long. Each folder can have up to 8 trees. For Joliet in the expansion format (file and folder names can have up to 64 characters) make sure of the contents of the writing software, etc. *2Multi Session This is a recording method that enables adding of data using the Track-At-Once method

28、. 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.

However, note that playback of some discs may not be possible depending on the recording device used for recording or the disc condition. Discs recorded on CD-R/CD-RW drives may not be played back b

31、ecause of scratches, dirt, recording condition or the drivers characteristics. CD-R and CD-RW discs that have not been correctly finalized (processing to allow play by a normal CD player) cannot be played. CD-R and CD-RW discs recorded in multi- session that have not ended by “closing the session” a

32、re not supported. The system may be unable to play MP3/JPEG format files that do not have the extender “.MP3”, “.JPG”, or “.JPEG”. Attempting to play non-MP3/JPEG format files that have the extender “.MP3”, “.JPG”, or “.JPEG” may result in noise or malfunction. Playback is possible up to 8 levels. W

33、ith 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. a disc recorded with complicated tree structure. a disc recorded in Multi Session. a disc to which data can be added (non- finalized disc

34、). Some CD-Rs, CD-RWs, DVD-Rs or DVD- RWs (in video mode) (DVD-RWs created in video mode have the same format as a DVD VIDEO) 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

35、will not play if it has not been correctly finalized. For more information, see the operating instructions for the recording device. A disc recorded in packet write format cannot be played. Note on playback operations of DVDs and VIDEO CDs Some playback operations of DVDs and VIDEO CDs may be intent

36、ionally set by software producers. Since this system plays DVDs and VIDEO CDs according to the disc contents the software producers designed, some playback features may not be available. Also, refer to the instructions supplied with the DVDs or VIDEO CDs. Copyrights This product incorporates copyrig

38、ng or disassembly is prohibited. 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 by some record companies. P

39、lease 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 This system can play Multi Session CDs when an MP3 audio track is contained in the first session. Any s

40、ubsequent MP3 audio tracks recorded in later sessions can also be played back. This system can play Multi Session CDs when a JPEG image file is contained in the first session. Any subsequent JPEG image files recorded in later sessions can also be played back. If audio tracks and images in music CD f

41、ormat or video CD format are recorded in the first session, only the first session will be played back.
