6-1-3 Replace the Filters
Dirty filter may reduce the air flowing into the projector and the temperature in the projector may rise as a
result. This may activate the protection mechanism or damage the components. Suggest changing the filter
each 2,000 hours. If the environment is quite dirty, you can check the filter status each 500 hours. If the filter
is still too dirty, please directly exchange it.
