Maintenance and Cleaning
Cleaning the Filter
Filter prevents dust from accumulating on the optical elements inside the projector. Should the filter becomes clogged with dust particles, it will reduce cooling fans’ effectiveness and may result in internal heat buildup and adversely affect the life of the projector. If a “Filter warning” icon appears on the screen, clean the filter immediately. Clean the filter by following the steps below.
1 | Turn off the projector, and unplug the AC power cord |
| from the AC outlet. |
2 | Turn the projector over and remove the filter by pulling |
| the latches upward. |
3 | Gently clean the filter by using a brush or rinse it |
| softly. |
4 | When rinsing the filter, dry it well. Replace the filter |
| properly. Make sure that the filter is fully inserted to |
the projector.
CAUTION
Do not operate the projector with the filter removed. Dust may accumulate on the optical elements degrading picture quality.
Do not put anything into the air vents. Doing so may result in malfunction of the projector.
RECOMMENDATION
We recommend avoiding dusty/smoky environments when you operate the projector. Usage in these environments may cause poor image quality.
When using the projector under dusty or smoky conditions, dust may accumulate on a lens, LCD panels, or optical elements inside the projector degrading the quality of a projected image. When the symptoms above are noticed, contact your authorized dealer or service station for proper cleaning.
