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 REPLACING THE FUSE

Be sure to use a fuse of the specified rating (10A) when replacing a blown fuse. Fuses with higher capacity ratings,use of any substitute, or connection without a fuse may result in a fire hazard or damage to the unit.

4 MAINTENANCE

Your product is designed and manufactured to ensure a minimum of maintenance. Use a soft cloth for routine exterior cleaning. Never use benzine, or other solvent.

5 RADIO ALIGNMENT

Do not align the AM/FM package blocks. When the package block is necessary, it will be supplied already aligned at the
