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. 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. See “ NOTE :
Use only approved accessories.” on page 39 for information. Use only a
replacement lamp (see “Optional Accessories” on page 39 for the part num-
ber) with the same type and rating as the original lamp.
