Cleaning Or Replacing The Filter
The air-filter sponge keeps the inside of the MultiSync MT600 LCD 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.
NOTE: Clean your filter after every 100 hours of operation.
To clean or replace the air-filter:
1. Turn off the LCD projector and wait for the fan to stop. Turn off the main power and
disconnect the power cable.
2. Remove the filter panel by pushing down on the cover until you feel it detach.
3. Replace it with a new filter or vacuum the filter thoroughly. Do not wash the filter
with soap and water. Soap and water will damage the filter membrane.
4. Reposition the filter or put the new filter into place. Reinstall the filter panel.
