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 sol-
der; Typically the melting point is 50 - 70
°
F (30 - 40

Replacing the Fuse
Use fuses of the same specified rating 15 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.
