Lead-free Solder

All boards mounted in this unit use unleaded solder. Be sure to use unleaded solder when repairing the boards of this

unit. A lead free mark (LF) indicating that the solder contains no lead is printed on each board. (Caution: Some printed

circuit boards may not come printed with the lead free mark due to their particular size.)

: LEAD FREE MARK

Notes

• The unleaded solder melts at a temperature about 40 °C higher than the ordinary solder. Therefore, it is

recommended to use a soldering iron having a temperature regulator.

• The ordinary soldering iron can be used but the iron tip has to be applied to the solder joint for a slightly longer

time. The printed pattern (copper foil) may peel away if the heated tip is applied for too long, so be careful.
