Replacing the lamp

• To reduce the risk of electrical shock, always turn the projector off and disconnect the power cord before changing the lamp.

•To reduce the risk of severe burns, allow the projector to cool for at least 45 minutes 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.

•To reduce the risk of injuries to fingers and/or compromising image quality by touching the lens, do not touch the empty lamp compartment when the lamp is removed.

•This lamp contains mercury. Consult your local hazardous waste regulations to dispose of this lamp in a proper manner.

•To assure optimal performance from the projector, it is recommended that you purchase a BenQ projector lamp for lamp replacement.

•If lamp replacement is performed while the projector is suspended upside-down from the ceiling, make sure that no one is underneath the lamp socket to avoid any possible injury or damage to the human eyes caused by fractured lamp.

1.Turn the power off and disconnect the projector from the wall socket. If the lamp is hot, avoid burns by waiting for approximately 45 minutes until the lamp has cooled.

2.Turn the projector over. Then use a coin to

turn the screw counterclockwise until the lamp cover loosens.
