recommended. Refer to this guide for proper  startup and shutdown procedures. This product has a lamp which cont ains a very small amount of mer
-
cury. Wash hands after cleaning the area and handling the ruptured 
lamp. Dispose of it as required by local, state or federal ordinances and 
regulations. For more information see www.eiae.org.
 In the unlikely event of a lamp rupture, particles may exit through the 
projector side vents. When the projector is turned on, keep people, 
food, and drinks out of the keep ou t area under and around the pro
