AT&T CL80111 user manual Experience poor sound quality when using the speakerphone

Appendix

Troubleshooting

I get noise, static, or weak signals even when I’m near the telephone base.

•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. The filter prevents noise and caller ID problems as a result of DSL interference. Please contact your DSL service provider for more information about DSL filters.

•You may be able to improve the performance of your cordless phone by installing your telephone base as far as possible from any other existing cordless telephone system that may already be installed.

•Other electronic products such as HAM radios and other DECT phones can cause interference with your cordless phone. Try installing your phone as far away as possible from these types of electronic devices.

•Do not install this phone near a microwave oven or on the same electrical outlet. You may experience decreased performance while the microwave oven is operating.

•If you plug your phone in with a modem or a surge protector, plug the phone (or modem/surge protector) into a different location. If this does not solve the problem, relocate your phone or modem farther apart from one another, or use a different surge protector.

•Move your phone to a higher location. The phone may have better reception in a high area.

•If other phones in your home are having the same problem, contact your telephone service provider (charges may apply).

I experience poor sound quality when using the speakerphone.

•For increased sound quality while using the speakerphone, place the handset on a flat surface with the dialing keys facing up.
