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 overheat.
CAUTION
• Turn off the projector, turn off the main power switch
and unplug 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.
To reset the filter usage time, from the menu, select [De-
fault]
→ [Clear Filter Usage].
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 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.
