Maintenance
Cleaning the Lens
1 Apply 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.
2 Lightly 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. Twenty hours before the lamp life expires, the
message “Change lamp” appears on the screen at startup. If the maximum
lamp time 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. See the Packing
list for information. Use only a replacement lamp with the same type and
rating as the original lamp.
1 Turn off the projector and unplug the power cord.
2 Wait 30 minutes to allow the projector to cool thoroughly.
3 Turn 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.
