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 : · 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) · This lead free solder will be used for the products after serial No. 1,000,001.

3 REPLACEING THE FUSE
Use fuses of the same specified rating 25 amps. Using different substitutes or fuses with higher ratings, or connecting the unit directly without a fuse, could cause fire or damage to the stereo unit.
