Maintenance

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

Optional long throw and short throw lenses are available. See “Optional Accessories” on page 41 for ordering information.

1Turn off the projector and unplug the power cable.

2Set the projector upright with the lens facing upward, place a screw- driver or other narrow object in the release hole on the bottom of the projector, then twist the lens counterclockwise to remove it.

3To install the new lens, align the red dot (near the base of the lens) with the top of the projector and turn clockwise until you feel the lens click into place.
