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 40C 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 350C. 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.

Note on DualDiscs

A DualDisc is a two sided disc product which mates DVD recorded material on one side with digital audio material on the other side. However, since the audio material side does not conform to the Compact Disc (CD) standard, playback on this product is not guaranteed.
Notes When naming an MP3/WMA file, be sure to add the file expansion.mp3 /.wma to the file name. During playback of a VBR (variable bit rate) MP3/ WMA file or fast-forward/reverse, elapsed playing time may not display accurately. When the disc is recorded in Multi Session, only the first track of the first session format is recognized and played (any other format is skipped). The priority of the format is CD-DA, ATRAC CD and MP3/WMA. When the first track is a CD-DA, only CD-DA of the first session is played. When the first track is not a CD-DA, an ATRAC CD or MP3/WMA session is played. If the disc has no data in any of these formats, NO MUSIC is displayed. Notes on MP3 Be sure to finalize the disc before using on the unit. If you play a high-bit-rate MP3, such as 320 kbps, sound may be intermittent. Notes on WMA Files made with lossless compression are not playable. Files protected by copyright are not playable.
