■ When to replace the lamp unit z
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 installation environment. Earlier replacement of lamp units is recommended for this reason.
The duration exceeds 2 200 hours of usage for two lamps, the lamps will be switched to the other two lamps if
they are available. After switching, if the duration exceeds 2 200 hours of usage for one of the two lamps and
the lamp fails, only the other lamp will light.
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.
