Maintenance
NOTE: When you are performing maintenance activities on your projector,
keep in mind that you should only remove screws that are single-slot, or
flathead, screws. Any other type of screw, such as a phillips or star should
not be removed. These types of screws should only be removed by technical
support experts.

Cleaning the lens

1Apply a non-abrasive camera lens cleaner to a soft, dry cloth.
Avoid using an excessive amount of cleaner, and don’t apply the
cleaner directly to the lens. Abrasive cleaners, solvents or other harsh
chemicals might scratch the lens.
2Lightly wipe the cleaning cloth over the lens in a circular motion. If you
don’t intend to use the projector immediately, replace the lens cap.

Changing the lens

Long throw and short throw lenses are available with your projector.
1Turn off the projector and unplug the power cable.
2Turn the projector upright with the lens facing upward and use a screw-
driver to remove the two screws from the front bezel release holes on the
bottom of the projector.
3Lift off the front bezel.
4Gently place a flathead screwdriver into the slot on the top of the projec-
tor (it is by the right speaker) and slide the small lever toward the right
speaker. The cover that protects the lens and the lamp housing pops up.
5Loosen the captive screw to the door that covers the lens housing.
