Type of discs Label on the disc
Audio CD
MP3 files
• Some CD-Rs/CD-RWs (depending on the equipment used forits recording or the condition of the disc) may not play on thisunit.
• You cannot play a CD-R/CD-RW that is not finalized∗.• You can play MP3 files recorded on CD-ROMs, CD-Rs, and
CD-RWs.• A CD-R/CD-RW to which a session can be added can be played.
∗ A process necessary for a recorded CD-R/CD-RW disc to beplayed on the audio CD player.
EXTENSION CABLE AND SERVICE POSITIONWhen repairing or servicing this set, connect the jig (extension cable)as shown below.
• Connect the MAIN board (CN751) and the SERVO board (CN2)with the extension cable (Part No. J-2502-076-1).
z UNLEADED SOLDERBoards requiring use of unleaded solder are printed with the leadfree 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 higher than
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 if theheated tip is applied for too long, so be careful!
• Strong viscosityUnleaded solder is more viscous (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.
