remote directly at the projector. Provided you are not holding the remote perpendicular to the sides or the 
rear of the projector, the remote will function well within a radius of about 7 meters (23 feet) and 15 
degrees above or below the projector level. If the projector does not respond to the remote control, move a 
little closer. 
Projector and Remote Control Buttons 
The projector can be operated using the remote control or the buttons on the top of the projector. All 
operations can be carried out with the remote control; however, the buttons on the projector are limited in
