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

• •

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.

2 FEATUERS

•

• 18-FM, 6-AM presets with preset scan

• •

•

• Digital servo for reliable CD playback.

• •

•

• Removable face plate.

• •

4 REPLACEING THE FUSE

Use fuses of the same specified rating (15A). Using different substitutes or fuses with higher ratings, or connecting the product directly without a fuse, could cause fire or damage to the stereo unit.

5 MAINTENANCE

Your products 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.

6 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.

[CD DECK BLOCK]

This model has no servo alignment points because microcomputer controls the servo circuit.
