1.1. 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 sol-
der; 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)
1.2. Laser Products
1.3. Replacing the Fuse
Use fuses of the same specified rating 15 amps. Using different
substitutes or fuses with higher ratings, or connecting the unit
directly without a fuse, could cause fire or damage to the stereo
unit.
1.4. Maintenance
Your product is designed and manufactured to ensure a mini-
mum 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 already aligned at the fac-
tory.
[CD DECK BLOCK]
This model has no servo alignment points because microcom-
puter controls the servo circuit.
