Preventative Maintenance
Preventive maintenance consists of replacing the air filter when it is dirty, ensuring that
the screen is clean and free of smudges or scratches, and cleaning the mirrors if they
become smudged or dusty. The projection lamp has a service life of 3,000 hours and should
be replaced at that time for trouble-free operation.
Screen
Removing the screen provides service access to other replaceable modules from the front
of the VideoWall.
