REPLACING THE FILTER CARTRIDGE
Always power down and disconnect/disengage all power sources to the
projector before servicing or cleaning.
Allow the projector to cool for at least 45 minutes before the lamp cover is
opened. The inside of the projector can become very hot and may cause injury.
NOTE:
To maintain normal internal ventilation replace the filter unit periodically.
1. Use a vacuum cleaner to remove dust on and
around the filter cover (Figure 3-Top-Left).
2. Lift and pull the bottom clips to remove the filter
cover (Figure 3-Top-Right).
3. Pinch and pull the filter clips to remove the filter
unit (Figure 3-Bottom-Left).
4. Use a vacuum cleaner to remove dust on and
around the intake vents of the projector (Figure 3-

6. Install the filter cover.
NOTICES: 1)
Make sure the filter cartridge is
correctly inserted into the projector otherwise, the
projector cannot be turned on.
2)
Do not block the air
vents. Doing so may result in malfunction of the projector.
3)
When using the projector under dusty or
smoky conditions, dust may accumulate on a lens, liquid crystal panels, or optical elements inside the

are noticed, contact your authorized dealer or service station for proper cleaning.
