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

•

• Sound System with Spurting Realism

• •

(2-channel or 4-channel Power Amplifier)

•

• Powerful Heavy Bass

• •

(Stereo/Mono Power Amplifier) : CY-M7052EN/CY­M9054EN

•

• Radio Data System (RDS)

• •

•

• Not support 8 cm discs

• •

•

• Not compatible with MP3/WMA

• •

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

3 FUSE

•

• Use fuses of the same specified rating (15A).

• •

•

• Using different substitutes or fuses with higher rating, or

• •

connecting the unit directly without a fuse, could cause fire
or damage to the unit.

4 MAINTENANCE

•

• Wipe the unit with a soft dry cloth.

• •

•

• Never apply volatile liquids such as benzine and thinner to

• •

prevent damage.
