Replacing the Projection Lamp 
The projection lamp should be replaced when it burns out. It should only be r eplaced with a certified 
replacement part, which you can order from your local dealer.

b.  Do not dispose this product  with general household waste. 
c. Disposal of this product must be carried out in a ccordance 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 ve nt so that you do not suffer from the gas and

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.
