This section describes the simple maintenance procedures you should foll\
ow to clean the filters and replace the lamp.


 Cleaning or Replacing the Filters
The air-filter sponge keeps dust and dirt from getting inside the projec\
tor 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 fi\
lters.
• 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 replace the filter (sponge):
1. Remove the filter cover by pushing down on the catch of the cover until \
you feel it detach.
NOTE: The VT580 and VT480 have two filters; the VT58 and VT48 have one f\
ilter only.
Catch
2. Gently peel off the filter (sponge) and replace it with the new one.

3. Reinstall the new filter cover.4. Clear the filter hours used.
To reset the filter usage time, from the menu, select [Reset]  → [Clear Filter Hours].
( → page  48 for resetting the filter usage time.)
NOTE: Do not wash the filter with soap and water. Soap and water will damage the filter membrane. Before replacing the f\
ilter,
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 replacem ent
lamp.

 Cleaning the Cabinet and the Lens
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 scra\
tch or mar the lens.
