Appendix
Troubleshooting
• Your caller must be calling from an area that supports caller ID.
• Both your and your caller's telephone service providers must
use caller ID compatible equipment.
• Make sure the home area code is set correctly in the
telephone (see Home area code in the TL32100/TL32200/
TL32300 user's manual).
• If you subscribe to high-speed Internet service
(DSL - digital subscriber line) through your telephone line, you
must install a DSL filter between the telephone line cord and
the telephone wall jack (see Telephone base and charger
installation in the TL32100/TL32200/TL32300 user's manual).
The filter prevents noise and caller ID problems caused by
DSL interference. Please contact your DSL service provider for
more information about DSL filters.
My telephone does not receive caller ID when on a call.
• Make sure you subscribe to caller ID with call waiting features
provided by your telephone service provider. Caller ID features
work only if both you and the caller are in areas offering
caller ID service, and if both telephone service providers use
compatible equipment.
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.
