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.
• Since a pair of non-interchangeable lamps is designed for this projector, only the specified BenQ
projector lamp can be used for lamp replacement. Make sure the correct lamp is purchased
beforehand.
• 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.
