PREFACE
< RZ670/RW630 >
The service technician is required to read and follow the “Safety Precautions” and “Important Safety Notice” in this service manual.
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
    Lithium Battery
    Precaution
    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 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 soldering 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.
