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.

•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.

cover on the side of the projector until the lamp cover loosens.
