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.

Replacing the Projection Lamp

The lamp hours used timer in the About menu counts the number of hours the lamp has been in use. After 2,980 hours, the message “Change lamp” appears on the screen at startup. If the maximum lamp time of 3,000 hours is exceeded, the lamp will not light. In this case, after replacing the lamp you must reset the lamp hours by simultaneously pressing both Volume buttons on the keypad and holding them for 10 seconds.

NOTE: You can order new lamp housings from your dealer.

1Turn off the projector and unplug the power cord.

2Wait 30 minutes to allow the projector to cool thoroughly.

3Turn the projector on its side so that the lamp door is facing you. Using a flat-blade screwdriver, gently pry the lamp door from the projector by placing the screwdriver blade into the space between the top of the lamp door and the projector.
