Troubleshooting
No caller ID information while on a call.
Make sure your telephone service provider provides caller ID information
while you are on a call. This is sometimes known as caller ID on call
waiting or type 2 caller ID.
The telephone cannot display the caller ID information if another
telephone on the same line is in use. Make sure all extensions are on hook.
DISPLAY DIAL does not work.
A home area code must be programmed. If you try to dial a number
displayed on the screen before entering a home area code, you will be
prompted to enter the home area code. Enter the code or enter 000 if you
dial 10-digit telephone numbers, then press OPTIONS.
Screen incorrectly displays LINE IN USE.
Make sure the telephone line cord is connected properly.
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.
