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 :

0 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 i
10°C). In case of using high temperature soldering iron,
please be careful not to heat too long.

0 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

- Remote Control.

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

3 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.

4 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.
