Ce document d'entretien est destiné aux techniciens d'entretien expérimentés uniquement et n'est pas conçu pour une utilisation par le
grand public. Il ne contient pas des avertissements ou des mises en garde pour aviser les non-techniciens des dangers potentiels lorsqu'ils
tentent de réparer un produit. Les appareils alimentés par l'électricité doivent être révisés ou réparés uniquement par des techniciens pro-

CAUTION:
About lead free solder (PbF)
This projector is using the P.C.Board which applies lead free solder.
Use lead free solder in servicing from the standpoint of antipollution for the global environment.
Notes:
• Lead free solder: Sn-Ag-Cu (tin, silver and copper) has a higher melting point (approx. 217°C) than standard solder Typically the melt-
ing point is 30~40 °C higher. When servicing, use a high temperature soldering iron with temperature limitation function and set it to
370 ± 10 °C.
• Be precautious about lead free solder. Sn-Ag-Cu (tin, silver and copper) will tend to splash when heated too high (approx. 600°C or
higher).
• Use lead free solder for the P.C.Board (specified on it as “PbF”) which uses lead free solder. (When you unavoidably use lead solder,
use lead solder after removing lead free solder. Or be sure to heat the lead free solder until it melts completely, before applying lead
solder.)
• After solder to double layered P.C.Boards, check the component side for excess solder which may flow onto the opposite side.
About the identification of the lead free solder P.C.Board.
For the P.C.Board which applies lead free solder, the symbol as shown in the figure below is printed or stamped on the surface or the
back of P.C.Board.
