About leadfree 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
ahigh temperature soldering iron. Incase of the soldering iron
with temperature control,please set itto 700±20°F (370±10°C).
-Pb free solder will tend to splash when heated too high (about
1100°F/ 600°C).
When soldering or unsoldering, please completelyremove all of the
solder on the pins or solder area, and be sure to heat the soldering
points with the Pb free solder until itmelts enough.

6. HOW TO REPLACE THE LITHIUM BATTERY
(PROCEDURE)
1. Remove the Side (L) C.B.A.. (Refer to DisassemblyProcedures.)
2. Unsolder the Lithium Battery“VSB0407” and then replace the new
one. (See Fig. B1.)
Fig. B1
Note:
The lithiumbatteryis a critical component. (Type No.: VSB0407 ManufacturedbyPanasonic.)
It must neverbe subjectedtoexcessive heat ordischarge.
It must therefore onlybe fittedinequipment designedspecificallyforits use.
Replacement batteries must be of the same type and manufacture.
Theymust be fittedinthe same mannerand location as the original battery, withthe correct
polaritycontacts observed.
Donot attempt tore-charge the oldbatteryorre-use it foranyotherpurpose.
It shouldbe disposedof inwaste products destinedforburial ratherthanincineration.
