About lead free solder / mfifil \ / 9173M, \ T

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.

- Sn + Ag + Cu (tin + silver + copper)
- Sn + Cu (tin + copper)
- Sn + Zn + Bi (tin + Zinc + 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.
