Remote control
• The infrared signal operates by line-of-sight up to a distance of about 22 feet/7 m and within a 60-degree angle
of the remote sensor on the projector cabinet.
• The projector will not respond if there are objects between the remote control and the sensor, or if strong light
falls on the sensor. Weak batteries will also prevent the remote control from properly operating the projector.
