7m/22 feet
• 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.
Remote Control Precautions
• Handle the remote control carefully.
• If the remote control gets wet, wipe it dry immediately.
• Avoid excessive heat and humidity.
• If you will not be using the remote control for a long time, remove the batteries.
• Do not place the batteries upside down.
