Note
The Cisco TelePresence System can display information from multiple input devices during a meeting;
if multiple input devices are sending information, the projector displays the input from the last
presentation device sending information. If an input device image is not being seen on the projector
screen, try the following: for VGA devices, unplug the device from the VGA cable, wait 5 seconds, and
then plug the device back in; for document cameras: turn the camera off, wait 5 seconds, and then restart
the device.
