Replacing the lamp
Hg - Lamp contains mercury. Manage in accordance with local disposal laws. See 
www.lamprecycle.org.
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.
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
