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

•

• •

• Fully Motorized Front Panel

•

• •

• Innovated APM (Auto Preset Memory) method

•

• •

• Six Preset Modes (FLAT, ROCK, POP, VOCAL, JAZZ,

CLUB)

•

• •

• SQ7 (7 Bands Sound Quality)

•

• •

• CD Changer Control

•

• •

• DVD Changer Control

•

• •

• Customize the Display (Customize Function)

•

• •

• Delightful sound space thanks to system buildup

•

• •

• The difference among these models’ are mentioned below.

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
