Introduction 13
Infra-Red (IR) remote control sensor is located on the front of the projector. The remote
control must be held at an angle within 30 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.
