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 :
2

- 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.

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.
