Projector operations are performed using the remote controller that comes with it. Point the remote 
controller signal emitter at one of the signal receivers on the projector as you perform remote 
controller key operations. The maximum range of the remote controller signal is approximately 
5 meters (16.4 feet) (between signal emitter and receiver).
Important!
z To avoid running down the battery, store the remote control unit so its keys are not pressed 
inadvertently.
