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 FEATURES
• • •
• MP3/WMA Playback from CD-R/RW
• • •
• Full Digital CD Receiver
• • •
• Radio DSP
• • •
• Fully Motorized Front Panel
• • •
• 256×64 pixel 512-color OEL display (CQ-C9901N only)
• • •
• CS Auto (Circle Surround Automotive)
• • •
• Six Preset Modes (FLAT, POP, ROCK, VOCAL, JAZZ,
CLUB)
• • •
• SQ9 (9 Bands Sound Quality)
• • •
• Full Lineup of optional parts
• • •
• Innovated APM (Auto Preset Memory) method
• • •
• CD Changer Control
• • •
• DVD Changer Control
• • •
• Differences Among 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]
This model has no servo alignment points because
microcomputer controls the servo circuit
