Cleaning or Replacing the Filters
The air-filter sponge keeps the inside of the MultiSync MT840/
MT1040/MT1045 Projector free from dust or dirt and should be
cleaned after every 100 hours of operation (more often in dusty con-
ditions). If the filter is dirty or clogged, your projector may overheat.
CAUTION
Turn off the power and unplug the projector before re-
placing the filter.
Only clean the outside of the filter cover with a vacuum
cleaner.
Do not attempt to operate the projector without a filter
cover.
Your projector will not operate unless the filter cover is
installed correctly.
To clean the air-filter:
Vacuum the filter-through the filter cover.
