To replace the filters:

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)
