MAINTENANCE AND SECURITY 
Replacing the Projection Lamp 
The projection lamp should be replaced when it burns out. It should only be replaced with a certified 
replacement part, which you can order from your local dealer.  
 Important: 
a. The projection lamp used in this product contains a small amount of mercury. 
b. Do not dispose this product with general household waste. 
c. Disposal of this product must be carried out in accordance with the regulations of your local  
authority. 
 Warning: 
Be sure to turn off and unplug the projector at least 30 minutes before replacing the lamp. Failure to 
do so could result in a severe burn. 
 
 Caution: 
In rare cases the lamp bulb may burn out during normal operation and cause glass dust or shards 
to be discharged outward from the rear exhaust vent. 
Do not inhale or do not touch glass dust or shards. Doing so could result in injury. 
Always keep your face away from the exhaust vent so that you do not suffer from the gas and 
broken shards of the lamp. 
When removing the lamp from a ceiling-mounted projector, make sure that no one is under the 
projector. Glass fragments could fall if the lamp has been burned out.  
 IF A LAMP EXPLODES 
If a lamp explodes, the gas and broken shards may scatter inside the projector and they may come 
out of the exhaust vent. The gas contains toxic mercury. 
Open windows and doors for ventilation. 
If you inhale the gas or the shards of the broken lamp enter your eyes or mouth, consult the doctor 
immediately.

pressing the POWER button. 
 
2.  Allow the projector to cool down at least 
30 minutes.
