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

- Large-sized volume control.

- SQ (Sound Quality).

- SRS TruBass [CQ-C3503N].

- The AUX input terminal is equipped on the front panel.

- This manual is for 2 models CQ-C3503N and CQ-C3303N. The following

table describes the differences between 2 models.

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.
