Cleaning the Lens

Follow these steps to clean the projection 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.

3If you don’t intend to use the projector immediately, replace the lens cap.

Cleaning the Dust Filters

The dust filters catch dust and other particles in the air. If the fil- ters become clogged, the projector does not cool properly and may malfunction.

1Turn off the projector and unplug the power cord.

2Turn the projector upside down and remove the screws on the filter doors.
