1. ABOUTLEADFREE SOLDER (PbF)
Distinction ofPbF PCB:
PCBs(manufactured)using leadfree solderwill have aPbF stampon thePCB.
Caution :
-Pbfree solderhas ahighermelting pointthanstandardsolder;
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 beusedfortheproducts afterserial No.

4. REPLACING THE FUSE
Use fuses ofthesamespecifiedrating (15amps). Using differentsubstitutes or fuses withhigher
ratings, or connecting theproductdirectlywithoutafuse, couldcause fireor damagetothe
stereounit.
5. MAINTENANCE
