Cleaning the Parts
You should clean the projector if it becomes dirty or if the quality of projected images starts to deteriorate.
Warning
Do not use sprays that contain flammable gas to remove dirt and dust from the projector's air filter, and
so on. The gases may ignite and result in fire.
Cleaning and replacing the air filter
Clean the air filter if dust has accumulated on the air filter or when the following message is displayed.
"The projector is overheating. Make sure nothing is blocking the air vent, and clean or replace the air
filter."
Attention
•
If dust collects on the air filter, it can cause the internal temperature of the projector to rise, and this can lead
to problems with operation and shorten the optical engine's service life. It is recommended that you clean
the air filter periodically. Clean more frequently if you are using the projector in a particularly dusty
environment.
•
Do not rinse the air filter in water. Do not use detergents or solvents.
•
Lightly brush the air filter to clean it. If it is brushed too strongly, dust will be ground into the air filter and
cannot be removed.
c
Dispose of used air filters properly in accordance with your local regulations.
