1. ABOUTLEADFREE SOLDER(PbF)

Distinction of PbF PCB:

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

Caution :

-Pbfree solderhas ahighermelting pointthanstandard solder;

Typicallythemelting pointis50 -70°F(30 -40°C) higher. Please

use asoldering iron withtemperaturecontrol and adjust itto700 ±

20°F(370 ±10°C). Incase ofusing high temperaturesoldering

iron, please becareful nottoheat too long.

-Pbfree solderwill tend tosplashwhenheatedtoo high (about

1100°F/600°C)

-Thisleadfree solderwill beusedfor theproducts afterserial No.

3. REPLACINGTHE FUSE

Use fuses of the same specifiedrating (3amps). Using different substitutes orfuses with higher

ratings, orconnecting the productdirectlywithout a fuse, couldcause fire ordamage to the

stereounit.

4. MAINTENANCE

Yourproductis designedand manufacturedto ensure a minimum of maintenance. Use a dry, a

soft cloth forroutine exteriorcleaning. Neveruse benzine, thinnerorothersolvents.
