Power And Connectivity Issues - LifeSize User Manual

Distorted Audio
Ensure that speakers are not obscured or damaged at either end of the call. Do not stack
items on top of the phone. 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. If an external speaker system has its own volume control, adjust
the volume to near maximum (in the range from 7-10) on the LifeSize audio output and
adjust the volume control on the external speaker system for the best results.

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 7 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.
