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.
2. FEATURES
- MP3/WMA Playback from CD-R/RW
- Fully Motorized Front Panel
- Six Preset Modes (FLAT, ROCK, POP, VOCAL, JAZZ, CLUB)
- SQ7 (7 Bands Sound Quality)
- DVD Changer Control
- Delightful sound space thanks to system buildup
- Maximum Power Output 50W
- Pre Out Fix Tipe (Silver)
3. REPLACEING 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.
4. MAINTENANCE
Your products is designed and manufactured to ensure a minimum of maintenance. Use a soft cloth for
routine exterior cleaning. Never use benzine, thinner or other solvent.
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 factory.
[CD DECK BLOCK]
This model has no servo alignment points because microcomputer controls the servo circuit
