Remote Control - Receiver Range

To ensure proper function of the remote control follow the steps below:

1. The remote control must be held at an angle within 30° perpendicular to the projector’s IR remote control sensor(s).
2. The distance between the remote control and the sensor(s) should not exceed 8 m (26 ft).

Note: Refer to the illustration for the location of the infrared (IR) remote control sensor(s).
