Make sure the projector is unplugged. Grasp the lens assembly near the point
where it enters the projector and slowly unscrew (counter-clockwise) until the
assembly is free from the projector. Use both hands and take care not to touch
the lens surface, which is easily damaged. Set aside.
NOTE: To remove a motorized zoom lens, loosen the 3 thumbscrews securing
the zoom adapter collar to the lens zoom ring. These screws are located around
the perimeter of the collar. Remove both the lens and the adapter collar.

Make sure the new lens is protected by the lens cap. Install
the new lens in the projector by carefully screwing the assembly into the
projector just until snug. If the lens assembly seems difficult to turn, it may be
cross-threaded. Carefully remove and try again. Use both hands and do not force
or over-tighten.
