To replace the filters:
Filter removal procedure is different depending on the model. Follow the procedure suitable for your model.
Four filters are packaged with the replacement lamp.
Honeycomb filter (coarse mesh): Large and small sizes (attached to the filter unit)
Accordion filter (fine mesh): Large and small sizes (attached to the filter cover)
NOTE:
• Replace all four filters at the same time.
• Before replacing the filters, wipe off dust and dirt from the projector cabinet.
• The projector is precision equipment. Keep out dust and dirt during filter replacement.
• Do not wash the filters with soap and water. Soap and water will damage the filter membrane.
• Put filters into place. Incorrect attachment of a filter may cause dust and dirt to get into the inside of the projector.
Before replacing the filters, replace the lamp. (→ page 120)
