Replacing the Dust Filter
Be sure to follow the steps to replace the dust filter.
The dust filter should be cleaned or replaced periodically (suggest

projector from being ventilated properly. This can cause over 
heating and damage the projector. If the projector is used in a dusty 
environment, be sure to cleaned or replaced the dust filter more 
frequently.
