1 ABOUT LEAD FREE

SOLDER (PbF)

Distinction of PbF PCB:

·PCBs (manufactured) using lead free solder will have a PbF stamp on the PCB.

Caution :

2FEATURES

·PLL (Phase Locked Loop) synthesized tuning

·MP3/WMA playback from CD-R/RW

·ALPS Tuner Pack (Digital Tuner)

·Illumination Color-Amber

·Pb free solder has a higher melting point than standard solder; Typically the melting point is 50 - 70°F (30 - 40°C) higher. Please use a soldering iron with temperature control and adjust it to 700 ± 20°F (370 ± 10°C). In case of using high temperature soldering iron, please be careful not to heat too long.

·Pb free solder will tend to splash when heated too high (about 1100°F/600°C).
