Troubleshooting

My calls cut in and out when I am using the telephone.

Other electronic products can cause interference to your telephone. Try installing your telephone as far away as possible from the following electronic devices: wireless routers, radios, radio towers, pager towers, cellular telephones, digital telephones, room monitors, televisions, VCRs, personal computers, kitchen appliances, wireless routers, and other cordless telephones.

If you have a headset plugged into the telephone, try unplugging it and firmly plugging it in again.

If your telephone is plugged in with a modem or a surge protector, plug the telephone (or modem/surge protector) into a different location. If this doesn't solve the problem, relocate your telephone or modem farther apart from each other, or use a different surge protector.

Disconnect the telephone base from the modular jack and plug in another corded telephone. If the calls are still not clear, the problem is probably in the wiring or local service. Contact your local service company (charges may apply).

Do you have DSL service? If yes, you need to have a DSL filter installed. Contact your DSL service provider for a DSL filter.
