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 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.

These marks denote that a disc is not for audio use.

� Some CD-Rs/CD-RWs (depending on the equipment used for its recording or the condition of the disc) may not play on this unit. � You cannot play a CD-R/CD-RW that is not finalized�. � A process necessary for a recorded CD-R/CD-RW disc to be played on the audio CD player.
