Maintenance of Projector  
 
 
 
 
WARNING  
The projector uses a high-pressure mercury lamp. 
The explosion of lamp with a loud bang or burn out could possibly cause injury or a fire. 
When the bulb bursts, it is possible for shards of glass to fly into the lamp housing and 
for gas containing mercury to escape from the projector‟s vent holes. 
If the lamp has broken, do not check the inside of the projector. Ventilate the room 
immediately. 
Do not touch or bring your face close to the broken pieces since it might get into your 
eyes or mouth. In case of injury, seek medical advice immediately.
