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 FEATUERS
• • •
• Hands Free Phone System. (The optional Bluetooth hands-
free kit: CY-BT100U)
• • •
• Expansion Module (The optional Hub unit: CY-EM100U)
• • •
• The optional adapter allows you to connect the optional
Panasonic DVD changer unit (CX-DH801U).
• • •
• 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.
• • •
• XM Satellite Radio. (The optional XM receiver: XMD-1000)
• • •
• Sirius Satellite Radio. (The optional Sirius Satellite receiver:
SIR-PAN1)
• • •
• SQ7 (7-Band Sound Quality) .
• • •
• D.M(Direct Memory)
• • •
• Customize the Display (Customize Function)
• • •
• MP3/WMA/AAC Playback from CD-R/RW.
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
