cause serious vision problems.
Keep small children away from the projector. Children can be severely burned by the hot lens. 
Also, children are more likely to look directly into the lens.
 Never touch the lens or the lamp when hot or warm; doing so will cause a severe burn. Unplug the 
projector and allow it to cool for 45 minutes before replacing the lamp or storing the projector. 
 Do not service the unit yourself; doing so could cause injury.
 Do not operate the projector near water or in a humid area. Do not place drinks on or near the 
projector; doing so could cause a burn or short an electrical circuit.
