46 Maintenance
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 loosen the screw on
the lamp cover.
3. Remove the lamp cover from the projector.
Do not turn the power on with the lamp cover
removed.
4. Loosen the screw that secures the lamp.
5. Lift the handle so that it stands up. Use the handle
to slowly pull the lamp out of the projector.
Pulling it too quickly may cause the lamp to
break and scatter broken glass in the
projector.
Do not place the lamp in locations where
water might splash on it, children can reach
it, or near flammable materials.
Do not insert your hands into the projector
after the lamp is removed. If you touch the
optical components inside, it could cause
color unevenness and distortion of the
projected pictures.
