Cleaning or Replacing the Filters
The air-filter sponge keeps the inside of the MultiSync MT1055/MT1050/
MT850 Projector free 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 power 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 a filter cover.
• Your projector will not operate unless the filter cover is installed cor-
rectly.
To clean the air-filter:
Vacuum the filter-through the filter cover.
