Remote control
Remote sensor on the
projector cabinet
• The infrared signal operates by line-of-sight up to a distance of about
22 feet / 7 m and within a 55°(Front) / 60°(Rear) angle of the remote
sensor on the projector cabinet.
• The projector will not respond if there are objects between the re-
mote 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.
