Troubleshooting

•If your phone is plugged in with a modem or surge protector, plug the phone (or modem/surge protector) into a different location. If this doesn’t solve the problem, re-locate your phone or modem farther apart from one another, or use a different surge protector.

•Relocate your telephone base to a higher location. The phone will have better reception when not installed in a low area.

•If the other phones in your home are having the same problem, the problem is in your wiring or local service. Contact your local telephone company (charges may apply).
