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 qualified 
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.
• 
Ensure good ventilation when handling broken lamps. We recommend that you use respirators, safety 
glasses, goggles or face shield and wear protective clothing such as gloves. 
1.
Turn the power off and disconnect the projector from the power outlet. If the lamp 
is hot, avoid burns by waiting for approximately 45 minutes until the lamp has 
cooled.
2.
Loosen the screw(s) that secures the lamp 
cover on the side of the projector until the 
lamp cover loosens.
3.
Remove the lamp cover from the projector.
• 
Do not turn the power on with the lamp cover 
removed.
• 
Do not insert your fingers between the lamp and the 
projector. The sharp edges inside the projector may 
cause injuries.
