CAUTION
 

 

 

Never use this projector at an altitude of 3 000m or higher.

 

 

Using this projector at high altitude, consult your dealer or Authorized Service Center about preparations.

 

 

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.

 

 

 

•  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.
