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. LASER PRODUCTS

3. FEATUERS

- Digital servo for reliable playback.

- PLL (Phase Locked Loop) synthesized tuning.

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

- Removable face plate.

- MP3/WMA Playback from CD-R/RW.

4. REPLACING THE FUSE

Use fuses of the same specified rating (15amps). 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 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.

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.
