This section includes basic troubleshooting information. For detailed
troubleshooting information, refer to Chapter 6, Troubleshooting.
Remote control not working.
Make sure the batteries are installed. Make sure you are pointing the
remote control at the ViewStation FX or the VS4000 IR detector. If
battery power is low, a low battery icon appears on the main screen.
Software Update appears when you power on the ViewStation
FX and VS4000.
The system software is corrupt or not loaded properly. Load system
software on the ViewStation FX or VS4000 from your PC. For
instructions on how to do this, refer to the Upgrading Software
section of Chapter 3, Using the ViewStation FX and VS4000 with a
PC, or consult your network equipment provider.
A lightning bolt indicator appears on the left side of your far or
near site screen.
The lightning bolt is only a visual indicator that informs you about
WAN or LAN network problems. It does not indicate performance
problems with your ViewStation FX or VS4000.
If you are in an H.320 call, the lightning bolt will most likely indicate
that the telephone company is experiencing bit errors on the line.
Contact and inform your telephone company of the existing problem.
If you are in an H.323 call, the lightning bolt may signify that your
LAN network is experiencing packet loss, accompanied by video
and audio degradation. Contact your network manager.
The lightning bolt works differently in H.320 and H.323 calls for
version 2.5 and above:
• In H.320 calls, the lightning bolt appears if there are 3 or more
CRC (Cyclic Redundancy Check) errors within a period of one
second, or if there are 10 or more FEC (Forward Error
Correction) errors in a period of one second.
