When to replace the lamp unit
The lamp unit is a consumable component. Since its brightness gradually decreases over time, it is necessary to replace the lamp unit 
regularly. The estimated duration before replacement is 3  000 hours, but the lamp may go off before reaching 3   000 hours, depending on 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, because it 
may cause malfunction of the projector.
If the runtime of all the four lamp units exceeds 3
  000 hours, the power will be switched off after approximately 10 minutes.
On-screen display
REPLACE LAMP

Note
 f
To predict when to replace the lamp, check the lamp runtime displayed in [LAMP1] to [LAMP4] of [STATUS] (x   page   106). fThe runtime of 3
  000 hours is a rough estimate and is not guaranteed.
