To replace the Filter (A):
NOTE:
• 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 Filter (A), make sure to replace the lamp and Filter (B). (→ page 119)
1. Pinch the knob at the bottom of the filter case and pull it out.
• If you put the projector upside down for replacing the Filter (A)
as the illustration, please lay a mat as a cloth for protecting the
cabinet top from damage.
2. Remove the Filter (A) from the filter case.
3. Vacuum all the dust on inside and outside of the filter case.
