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.  
 
Caution: 
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. 
 
Important: 
1. The lamp contains a certain amount of mercury and should be disposed of according to local or-
dinance regulations. 
2. Avoid touching the glass surface of the new lamp: Doing so may shorten its operation life. 
 
Warning: 
Be sure to turn off and unplug the projector at least an hour before replacing the lamp. Failure to do 
so could result in a severe burn. 
 
1.  Loosen the two captive 
screws on the lamp 
compartment cover (A).

Cleaning the Projector

could result in a severe burn. 
2. Use only a dampened cloth when cleaning. Do not allow water to enter the ventilation openings 
on the projector.  
3. If a little water gets into the projector interior while cleaning, leave unplugged in a well-ventilated 
room for several hours before using. 
4. If a lot of water gets into the projector interior when cleaning, have the projector serviced.

Cleaning the Lens 
You can purchase optic lens cleaner from most camera stores. Refer to the following to clean the pro-
jector lens. 
1. Apply a little optic lens cleaner to a clean soft cloth. (Do not apply the cleaner directly to the lens.) 
2. Lightly wipe the lens in a circular motion. 
Caution: 
1. Do not use abrasive cleaners or solvents. 
2. To prevent discoloration or fading, avoid getting cleaner on the projector case. 
Cleaning the Case 
Refer to the following to clean the projector case. 
1. Wipe off dust with a clean dampened cloth. 
2. Moisten the cloth with warm water and mild detergent (such as used to wash dishes), and then wipe 
the case. 
3. Rinse all detergent from the cloth and wipe the projector again. 
Caution: 
To prevent discoloration or fading of the case, do not use abrasive alcohol-based cleaners. 
Using the Kensington® Lock 
If you are concerned about security, attach the projector to a permanent object with the Kensington 
slot and a security cable.

ment, contact: Kensington, 2853 Campus Drive, San Mateo, CA94403, U.S.A. Tel: 800-535-4242,

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 con-
nection. 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 suspend 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 call-
ing for technical support or for passing on to service personnel.
