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 bro-
ken shards of the lamp. 
When removing the lamp from a ceiling-mounted projector, make sure that no one is under the pro-
jector. 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

TROUBLESHOOTING 
Common Problems and Solutions 
These guidelines provide tips to deal with problems you may encounter while using the projector. If the 
problem remains unsolved, contact your dealer for assistance. 
Often after time spent troubleshooting, the problem is traced to something as simple as a loose connection. 
Check the following before proceeding to the problem-specific solutions. 
 Use some other electrical device to confirm that the electrical outlet is working. 
 Ensure the projector is turned on. 
 Ensure all connections are securely attached.  
 Ensure the attached device is turned on. 
 Ensure a connected PC is not in suspending mode. 
 Ensure a connected notebook computer is configured for an external display. 
(This is usually done by pressing an Fn-key combination on the notebook.) 
Tips for Troubleshooting 
In each problem-specific section, try the steps in the order suggested. This may help you to solve the 
problem more quickly. 
Try to pin point the problem and thus avoid replacing non-defective parts.  
For example, if you replace batteries and the problem remains, put the original batteries back and go to 
the next step.  
Keep a record of the steps you take when troubleshooting: The information may be useful when calling for 
technical support or for passing on to service personnel.
