LifeSize Phone - Upgrading Your LifeSize Phone

12 LifeSize Video Communications Systems User Guide
Adjust the priority order for your audio codec (from the Preferences : Audio menu) if you
have chosen a low-bandwidth audio codec to be first.
Ensure that the far end caller has configured the phone correctly and is in an acoustically
benign environment. For best results, ensure the far end caller is using a LifeSize Phone.
Distorted Audio
Poor audio quality may result from a bad network connection. Ensure that your network
connection is capable of handling the correct bandwidth; LifeSize recommends that your
network connection be capable of at least 100Mbps (100-baseT) for best performance.
Also ensure the loudspeaker is not obscured or damaged at either end of the call. Do not
stack items on top of the phone. Do not use any kind of liquid or aerosol cleaner on the
phone. A soft, slightly damp cloth should be sufficient to clean the top surface of the phone if
necessary.
Restoring Default Settings
You may need to reset the phone to its default state (from the Maintenance : Reset menu)
to correct unknown problems you may be experiencing. If this reset fails, you can also
manually restore the phone to its default state. Remove power, press and hold the 7, 8, and
9 keys simultaneously, and then reapply power. Hold the keys down until the Initial
Configuration screen appears.
