Cleaning or Replacing the Filters
The air-filter sponge keeps the inside of the MultiSync LT156/LT155/

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.
