7. Maintenance
This section describes the simple maintenance procedures you should follow to clean the filters and replace the lamp.
Cleaning or Replacing the Filter
The air-filter sponge keeps dust and dirt from getting inside the projector 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 [Reset]

for resetting the filter usage time)
To replace the filter (sponge):
CAUTION
•
Replace both filters at the same time.
•
Before replacing the filters, remove dust and dirt from the projector cabinet.
•
The projector contains high-precision parts. Keep out dust and dirt during filter replacement.
•
Do not wash the filter with water. Water will damage the filter membrane.
•
Reattach the filter cover correctly. Failure to do so may cause projector malfunction.
Preparation:
Replace the lamp before replacing the filters.
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.
