1.1. About Lead Free Solder (PbF)
Distinction of PbF PCB :
• PCBs (manufactured) using lead free sol de r w ill ha ve 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 wi ll be sup pli ed alrea dy alig ne d at the fac tory.
[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 dam ag e to th e s tere o
unit.
