Maintenance and Cleaning
Cleaning the Filters
Filter prevents dust from accumulating on the optical elements inside the projector. Should the filters become 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 filters immediately. Clean the filters by following the steps below.
1 | Turn off the projector, and unplug the AC power cord |
from the AC outlet. | |
2 | Remove the panel front assembly by pulling the latch |
horizontally. | |
| Remove the panel net by pulling the latch horizontally |
| and then remove it leftward. |
3 | Clean the filters with a brush or rinse them softly. |
4 | When cleaning the filters by rinsing, dry them well. |
Replace the filters properly. Make sure that the filters |
are fully inserted.
CAUTION
Do not operate the projector with the filters 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.
