To get started double click on the CERN VIDYO PORTAL icon
Next log in with your CERN account.
Choose the name of a meeting or a person to contact. Click on its name in order to enter the "room". In the setup window choose "Phnx MT301" for speakers and microphone, and "Logitech HD Pro Webcam C910" for the camera.
The Setup button next to the Camera option takes you to the Logitech camera control page.
This gives limited control of pan tilt and zoom.
