Remote Control Effective Range
Infra Red (IR) remote control sensors are located on the front and the back of the projector.
The remote control must be held at an angle within 30 degrees of the projector’s IR remote
control sensors to function correctly. The distance between the remote control and the sen-
sors should not exceed 6 meters (19.5 feet).
Notes on Remote Control Operation:
Make sure that there are no obstacles between the remote control and the IR sensors on the
projector that might obstruct the infra-red beam.
