Cleaning and replacing the dust filters

Cleaning the dust filters

Clean the dust filters after every 1000 hours of use. If they are note cleaned

periodically, they can become clogged with dust, preventing proper ventilation.

This can cause overheating and damage the projector.

Follow these steps:

Turn the projector off. Wait for the Power LED to stop flashing then

unplug the power cord.

Allow the projector at least 30 mins to cool down.

Pull out the dust filter. (Illustration #1)

To clean the dust filters, use a small vacuum cleaner designed for

computers and other office equipment. (Illustration #2)

If the dirt is difficult to remove or the filter is broken, please contact your

local dealer or service center to obtain a new filter.
