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
•
• 18-FM, 6-AM presets with preset scan
• •
•
• Digital servo for reliable CD playback.
• •
•
• Removable face plate.

4 REPLACEING THE FUSE
Use fuses of the same specified rating (15A). 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 products 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.
