3 CD Playback You can play CD-DA (also containing CD TEXT*) and CD-R/ CD-RW (MP3/WMA files also containing Multi Session). Type of discs CD-DA MP3 WMA Label on the disc *A CD TEXT disc is a CD-DA that includes information such as disc, artist and track name. UNLEADED SOLDER Boards 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 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 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 applied for too long, so be careful! Strong viscosity Unleaded solder is more viscous (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 be added to ordinary solder. EXTENSION CABLE AND SERVICE POSITION When repairing or servicing this set, connect the jig (extension cable) as shown below.
