control at an angle within 40 degrees perpendicular to the projector's IR remote control sensor to function correctly.
The distance between the remote control and the sensor should not be longer than 5 meters (16.4 feet).
‡ Make sure that there are no obstacles between the remote control and the IR sensor on the projector
that might obstruct the infra-red beam.
‡ Make sure the IR transmitter of the remote control is not being illuminated by sunlight or fluorescent
lamps directly.
‡ Keep the remote control more than 2 meters away from fluorescent lamps or it may not function.
‡ When you aim at the screen the effective distance is 5 meters or less from the remote to the screen
then back to the projector. The range will be different based on the reflectivity of the screen.
