Maintenance

A lamp has a finite product life. Using the lamp for long periods of time could 

cause the pictures darker or the color tone poor. Note that each lamp has a 

different lifetime, and some may burst or burn out soon after you start using them. 

Preparation of a new lamp and early replacement are recommended.

To prepare a new lamp, contact your dealer and tell the lamp type number.

   

1.

Turn the projector off, and unplug the power cord. Allow the lamp to cool for 

at least 45 minutes.

2.

Prepare a new lamp.

If the projector is mounted on the ceiling, or if the lamp has broken, also ask 

the dealer to replace the lamp.

3.

After making sure that the projector has cooled adequately, slowly turn over 

the projector, so that the bottom is facing up.

4.

Please loosen the screw (marked by arrow). 

Then, unhook the claws of the lamp cover 

and remove the lamp cover.

5.

Loosen the 2 screws (marked by arrow) of 

the lamp, and slowly pick up the lamp by the 

handles.

Please be careful in handling the lamp. 

Breaking the lamp could cause an injury and 

an escape of gas containing mercury. 

6.

Insert the new lamp, and retighten firmly the 

2 screws that are loosened in the previous 

process to lock it in place.
