1.1. About Lead Free Solder(PbF)
Distinction of PbF PCB
• PCBs(manufacture)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 solder-
ing 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)
1.2. Maintenance
Your products is designed and manufactured to ensure a minimum of maintenance. Use a dry, a soft cloth for routine exterior clean-
ing. Never use benzine, thinner or other solvents.
1.3. Notes
[RADIO BLOCK]
Do not align the AM/FM package block. When the package block is necessary, it will be supplied already aligned at the factory.
