Notes

•When the air filter is dusty, the ventilation is impaired. This causes the temperature inside the projector to rise, and may damage the unit.

•Attach the air filter cover firmly after the cleaning. If it is not set correctly, the dusts will enter and they will be projected and overlapped on the picture.

•If you wash the air filter with water, be sure to let it dry fully before reinstalling it. Using it damp will result in malfunction.

•If the air filter is damaged, contact your store of purchase and replace it with a new one. Using a damaged air filter will cause dust or dirt to get inside the projector and onto the images.
