Important Safety Notices
Safety Instructions
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 dose not contain warnings or cautions to advise non-technical
individuals of potential dangers in attempting to service a product. Products 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.
• Use UV Radiation eye and skin protection during servicing.
• Precaution
• If using of this projector at high altitudes, “High Altitude” to “ON” for 1,000 to 3,000m.
(Refer to “PROJECTOR SETUP menu” in Operating Instructions.)
Failure to observe this may cause malfunctions. 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.
• 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.
• 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 to 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.
