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.

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.
