1. ABOUT LEAD FREE SOLDER (PbF)

Distinction of PbF PCB:

PCBs (manufactured) using leadfree solderwill have a PbF stampon the PCB.

Caution :

-Pb free solder has ahigher melting point than standard solder;

Typicallythe melting point is50 -70°F (30 -40°C)higher. Please

use asoldering iron with temperature control and adjust itto 700 ±

20°F (370 ± 10°C). Incase 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)

-Thislead free solder will be used for the products after serial No.

1,000,001.

2. LASER PRODUCTS

3. FEATUERS

-Large-sized volume control.

-SQ (Sound Quality).

-The AUXinput terminal isequipped on the front panel.

-Thismanual isfor 2modelsCQ-C3203Uand CQ-C3103U. The

following tabledescribes the differences among 2models.

4. REPLACING THE FUSE

Use fuses of the same specifiedrating (15amps). Using different substitutes orfuses with

higherratings, orconnecting the product directlywithout a fuse, couldcause fire ordamage to

the stereounit.

5. MAINTENANCE

Yourproduct is designedand manufacturedtoensure a minimumof maintenance. Use a dry, a

soft clothforroutine exteriorcleaning. Neveruse benzine, thinnerorothersolvents.

6. NOTES

[RADIO BLOCK]

Donot align the AM/FM package block. Whenthe package block is necessary, it will be supplied

alreadyalignedat the factory.

[CD DECK BLOCK]

This model has no servoalignment points because microcomputercontrols the servocircuit.
