IP Address Displays Invalid Value
If the IP address displays an invalid value, one of the following conditions may be occurring:
Poor Quality Display
If you have poor quality or unreadable data on the LifeSize Phone display, adjust the User
Preferences : LCD Contrast setting. The default setting (6) is recommended.
If the colors on the display appear incorrect verify that the RGB cable is properly connected
to the display.
If you experience poor motion handling or visible tiling in the far end picture during a video
call, check the following:
• You have adequate bandwidth for the data rate at which you are trying to establish the
call.
• The Internet or private line connection you are using is optimized for video calls.
• The switch/router configuration in your network is configured for full duplex 100-base T.
Missing Input
If you have not connected all possible video inputs, the input selection dialog displays a blue
image by default. If you select an input that is not connected, a full screen view of random
data displays. Connect the necessary input or choose a different input as described in
"Selecting Input" on page 16.
Unable to Display Presentations
If you are unable to display presentations as described in "Presentations" on page 18,
ensure you have disabled the H.245 tunneling preference. Access Administrator
Preferences : Communications : H.245 Tunneling. This preference is disabled by default.
