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.
