Notice on laser
This projector is the Class 1 laser product that complies with IEC 60825-1.
The class 4 laser module is mounted in the inside of a product.
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 melting point is 30~40 °C higher. When servicing, use a high temperature soldering iron with temperature limitation func-
tion 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.
