the characteristics of the individual lamp, usage conditions, and the installation environment. It is recommended that the Replacement lamp 
unit be prepared earlier.
If you continue to use the lamp unit after 3
  000 hours has elapsed, the lamp turns off automatically after approximately 10 minutes, as it may 
cause malfunction of the projector.
