Using the Remote Control
The remote control uses a line-of-sight infrared signal. It lets
you access the projector's features from anywhere in the
room—up to 32 feet away. (This distance may be shorter if
the remote control batteries are low.) If you have connected
the mouse cable, you can also use the remote control as a
wireless mouse.
The projector may not respond to remote control commands
in these conditions:
You are too far away or not within 30 to the left or right of
the front or rear sensor or 15 above or below
The
