Remote control effective range
There are infra-red (IR) remote control sensors located at the front and back of the
projector. Hold the remote control and maintain a perpendicular angle within 30 degrees
with the IR remote control sensor to achieve normal remote control functions. The distance
between the remote control and the sensor should not exceed 8 meters (about 26 feet).
Do not place any obstruction in front of the IR sensor on the projector as this may block
the IR beam.
