ViewStation User’s Guide
The Audio Meter screen indicates the audio level of all audio inputs connected 
to the ViewStation. 
Near-End Loop
The Near-End Loop screen allows you to test the encoder/decoder of your unit. 
This can help you diagnose a problem with a video call. If you send a near-end 
loop during a call, the far-site will see a loop of themselves. Press any button on 
the remote to stop the loop. When you are finished, highlight the Menu icon to 
return to the Diagnostics screen.
