Troubleshooting
I subscribe to a nontraditional telephone service that uses my computer to
establish connections, and my telephone doesn't work.
• Make sure your computer is powered on.
• Make sure your Internet connection is working properly.
• Make sure that the software is installed and running for your nontraditional
telephone service.
• Make sure to plug your USB telephone adapter into a dedicated USB port on
your computer. Do not plug into a multiple port USB hub (USB splitter) that
is not powered.
• In a few rare instances, the USB port on your computer may not have
enough power. In these instances, try using a USB hub with its own external
power supply.
• If you are using a firewall, it may prevent access to your nontraditional
telephone service. Contact your service provider for more information.
I've set my LCD language to Spanish or French and I don't know how to
change it back to English.
When the telephone is idle, press OPTIONS and then enter 3645474#.
•
The LCD language is reset to English and the telephone returns to idle
mode.
