Cleaning or Replacing the Filter
The air-filter sponge keeps the inside of the MultiSync GT2150 Projec-
tor 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, wait for three minutes, and unplug the projector
before replacing the filter.
• Only clean the outside of the filter with a vacuum cleaner.
• Do not attempt to operate the projector without filter.
• Your projector will not operate unless the filter is installed correctly.
To clean the filter:
Pull out the filter by pushing up on the catch. Vacuum the filter-through
the filter.
To replace the filter:
1. Pull out the filter by pushing up on the catch.
