Audio Issues; Power And Connectivity Issues - LifeSize Passport User Manual

Poor Quality Far End Video
During a call, the LifeSize system automatically selects the best video algorithm based on
the video source and capabilities of the remote system. If you experience poor motion
handling or visible tiling in the far end picture during a video call, contact your administrator.

Audio Issues

A LifeSize system automatically selects the best audio algorithm based on the call rate and
the capabilities of the remote system. The following issues are related to the audio quality.
Problematic Sound Quality
If you are unable to hear the ringer when an incoming call arrives, adjust the Ring Tone
Volume preference in User Preferences : Audio.
Muffled audio reception from the far side may be caused by highly reverberant rooms. If you
are experiencing poor audio reception, add more sound absorbency to the room and speak
in close proximity to the microphone.
Degradation in the audio quality can also be caused by faulty microphones or dust and
debris on the microphones. Do not use any kind of liquid or aerosol cleaner on LifeSize
devices that include microphones. A soft, slightly damp cloth is sufficient to clean the top
surface of the units if necessary.
Distorted Audio
Ensure that speakers are not obscured or damaged at either end of the call. Ensure both
ends are not muted. Verify that the audio out cables are properly connected to the display
and that any external speaker systems are powered and configured correctly.

Power and Connectivity Issues

If a call does not successfully connect, verify that you have dialed a working number and
that the far end destination is powered on and available. Verify that the network is ready and
available. Network status is indicated at all times in the status bar. If the LifeSize system is
connected to the local network, a green network status icon appears. A yellow or red
network status icon indicates a problem with the network connection. Refer to "The Main
Screen" on page 6 for a visual depiction and description of the network status icons.
You may need to reboot a system that is not responding to commands from the remote
control. To reboot the system, access User Preferences : Diagnostics : System Reboot.
