Maintenance and Cleaning
Air Filter Replacement
Air filters prevent dust from accumulating on the surface of the optical elements inside the projector. Should the air filters become clogged with dust particles, it will reduce cooling fans’ effectiveness and may result in internal heat build up and adversely affect the life of the projector. Proper maintenance should be taken.
WARNING FILTER Indicator
This projector can monitor the filter condition. When the filter is clogged with dust and the performance is degraded, the WARNING FILTER indicator lights orange and let you know the filter replacement is required.
If the indicator is lighting orange, turn off the projector and replace the air filter immediately.
Using the projector with the WARNING FILTER indicator lighting may result in internal heat build up and cause damage to the optical elements inside the projector. The projector will shutdown automatically to protect itself when the projector's inside temperature is abnormally high.
1 | Turn off the projector, and disconnect the AC power cord |
| from the AC outlet. |
2 | Pull down the tabs on both sides top of the filter cover and |
| open the projector cover. |
3 | Pull out the air filter from the projector. |
4 | Replace the new air filter and the filter cover properly onto |
| the projector. |
5 | Reset the Filter time. See “Filter” in the Special menu on |
| page 57. |
CAUTION
Do not operate a projector with Air Filter removed. Dust may accumulate on LCD Panel and Mirror degrading picture quality.
Do not put small parts into Air Intake Vents. It may result in malfunction of a projector.
RECOMMENDATION
We recommend avoiding dusty/smoky environments when operating a projector. Usage in these environments may cause poor image quality.
When using under dusty or smoky conditions, dust may accumulate on liquid crystal panel, lens, or optical elements inside it. This condition may degrade quality of projected image.
When above symptoms are noticed, contact your authorized dealer or service station for proper cleaning.
