About lead free solder l fiflal \79IZ'DLVZ

All of the P.C.B.s installed in this unit and solder joints are
soldered using the lead free solder.

Among some types of lead free solder currently available,
it is recommended to use one of the following types for
the repair work.

0 Sn + Ag + Cu (tin + silver + copper)

0 Sn + Cu (tin + copper)

0 Sn + Zn + Bi (tin + ZlnC + bismuth)

Caution:
As the melting point temperature of the lead free solder
is about 30°C to 40°C (50°F to 70°F) higher than that of
the lead solder, be sure to use a soldering iron suitable
to each solder.
