Important:
1. Avoid using the projector with bright fluorescent lighting turned on. Certain high-frequency fluo-
rescent lights can disrupt remote control operation.
2. Be sure nothing obstructs the path between the remote control and the projector. If the path be-
tween remote and projector is obstructed, you can bounce the remote signal off certain reflective surfaces such as projector screens.

Remote Control Operating Range

The remote control uses infrared transmission to control the projector. It is not necessary to point the remote directly at the projector. Provided you are not holding the remote perpendicular to the sides or the rear of the projector, the remote functions within a radius of about (7) meters (23 feet) and 30 de­grees above or below the projector level. If the projector does not respond to the remote control, move a little closer.
