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. FEATUERS
- Hands Free Phone System. (The optional Bluetooth hands-free kit: CY-
BT100N)
- Expansion Module (The optional Hub unit: CY-EM100N)
- The optional adapter allows you to connect the optional Panasonic DVD
changer unit (CX-DH801N).
- The optional adapter allows you to connect the optional Panasonic CD
changer unit (CX-DP880).
- The optional adapter allows you to connect the optional iPod series.
- SQ (Sound Quality).
- SQ7 (7-Band Sound Quality).
- Customize the Display (Customize Function)
- MP3/WMA Playback from CD-R/RW.
- This manual is for 2 models CQ-C7703N and CQ-C7703N. The following
table describes the differences between 2 models.
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]
