Remote control effective range
Infra-Red (IR) remote control sensors are located on the front and the back of the projector
with an incline of 45 degrees. The remote control is recommended to be held at an angle
within 30 degrees perpendicular to the projector's IR remote control sensors to function
correctly. The distance between the remote control and the sensors should not exceed 6
meters (~ 20 feet).
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.
Always aim the remote control at the projector's IR remote sensor; however most screens
will also refect the IR beam to the projector.
