The lamp unit is a consumable component. Replace the lamp unit regularly, as its brightness gradually decreases 
over time. The estimated duration before replacement is 2 000 hours (when [Lamp power] is set to standard). 
However, this may be shortened depending on individual lamp characteristics, usage conditions, and the installa-
tion environment. Earlier replacement of lamp units is recommended for this reason.
The duration exceeds 2 200 hours of usage for one lamp, the lamp will be switched to the other one if it is avail-
able. 
If the power is turned on without replacing the lamps after the duration exceeds 2 200 hours of usage for all lamps, 
the power automatically turns off after approximately ten minutes to prevent the malfunction of the projector.

• When replacing the lamp unit, be sure to hold it by the handle.
•  To prevent glass fragments from scattering, hold the lamp unit vertically when replacing it. When the projector

cover slowly.
