Infra-Red (IR) remote control sensor is located on the front of the projector. The remote 

control must be held at an angle within 15 degrees perpendicular to the projector's IR 

remote control sensor to function correctly. The distance between the remote control 

and the sensor should not exceed

 

8 meters (~ 26 feet).

Make sure that there are no obstacles between the remote control and the IR sensor on 
the projector that might obstruct the infra-red beam.
