The service technician is required to read and follow the “Safety Precautions” and “Important Safety Notice” in this service manual.

This service information is designed for experienced repair technicians only and is not designed for use by the general public.

It does not contain warnings or cautions to advise non-technical individuals of potential dangers in attempting to service a product. Prod-

ucts powered by electricity should be serviced or repaired only by experienced professional technicians. Any attempt to service or repair 

the product or products dealt with in this service information by anyone else could result in serious injury or death.

 

 

Risk of explosion if battery is replaced by an incorrect type,

 

 

Replace only with the same of equivalent type recommended by the manufacturer.

 

 

Dispose of used batteries according to the manufacturer’s instructions.

 

 

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.
