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.
