1.1. About Lead Free Solder (PbF)
Distinction of PbF PCB :
• PCBs (manufactured) using lead free solder will have a Pb F 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.
1.2. Laser Products
1.4. Maintenance
Your product is designed and manufactured to ensure a mini­mum of maintenance. Use a dry, a soft cloth for routine exterior
cleaning. Never use benzine, thinner or other solvents.
1.5. Notes
[RADIO BLOCK]
Do not align the AM/FM package block. When the package block is necessary, it will be supplied alrea dy alig ned at the fac­tory.
[CD DECK BLOCK]
This model has no servo alignment points because microcom­puter controls the servo circuit.
1.3. Replacing the Fuse
Use fuses of the same s pe cif ied rati ng 15 a mps. Using different substitutes or fuses with higher ratings, or connecting the unit directly without a fu se, could cause fire or damage to th e st ere o unit.
