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.
