before replacing the lamp.
To reduce the risk of injuries to fingers and damage to internal components, use caution
when removing lamp glass that has shattered into sharp pieces.

lamp is not replaced beforehand, it must be replaced
after 4000 hours usage.
If this warning message displays, the projector will
