Cleaning or Replacing the Filter
The air-filter sponge keeps the inside of the projector from dust or dirt
and should be cleaned after every 100 hours of operation (more often in
dusty conditions). If the filter is dirty or clogged, your projector may over-
heat.
CAUTION
• Turn off the projector, turn off the main power switch and un-
plug the projector before replacing the filter.
• Only clean the outside of the filter cover with a vacuum cleaner.
• Do not attempt to operate the projector without the filter cover.
To clean the air-filter:
Vacuum the filter-through the filter cover.
Catch
To reset the filter usage time, from the menu, select [Default] → [Clear
Filter Usage].
See also page E-24 for resetting the filter usage time.
To replace the filter (sponge):
1. Remove the filter cover by pushing up on the catch of the cover until
you feel it detach.
2. Gently peel off the filter (sponge) and replace it with the new one.
3. Reinstall the new filter cover.
NOTE: Do not wash the filter with soap and water. Soap and water will damage
the filter membrane. Before replacing the filter, remove dust and dirt from the
projector cabinet. Keep out dust and dirt during filter replacement.
NOTE: When you replace the lamp, it is also wise to replace the filter. The filter
comes in the same package with your replacement lamp.
1. Turn off the projector before cleaning.
2. Clean the cabinet periodically with a damp cloth. If heavily soiled,
use a mild detergent. Never use strong detergents or solvents such
as alcohol or thinner.
3. Use a blower or lens paper to clean the lens, and be careful not to
scratch or mar the lens.
