Notes on Remote Control Operation
In most situations, you can simply point the remote control at the screen which will reflect the IR signal from the re-
mote back toward the IR receiver on the projector. In some cases, however, ambient conditions may prevent this. If
so, point the remote control at the projector and try again.
If the effective range of the remote control decreases, or it stops working, replace the batteries with new ones.
The remote control may fail to operate if the infrared remote sensor is exposed to bright sunlight or fluorescent lighting.
