• If cleaning cannot remove the dust completely, then it is a sign to replace the air filter. Consult the
dealer. In addition, when the lamp unit is replaced, also replace the air filter.
Note
If too much dust is deposited in the air filter, temperature inside the main unit will rise and the temperature monitor
(TEMP) blinks, eventually turning off the power supply.
Clean the air filter section once every 100 hours or so as a guideline depending on the location of projector
operation.
