Troubleshooting

Problem

I cannot dial out

I hear other calls when using the telephone.

My caller ID features are not working properly

Suggestion

Make sure there is a dial tone before dialing. It is normal if the cordless handset takes

a second or two to synchronize with the telephone base before producing a dial tone. Wait an extra second before dialing.

Make sure the telephone is set to the correct dial mode (pulse dial or tone dial) for the service in your area.

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

Eliminate any background noise. Noise from a television, radio, or other appliances may cause the telephone to not dial out properly.

If you cannot eliminate the background noise, first try muting the cordless handset before dialing, or dialing from another room in your home with less background noise.

Disconnect the telephone base from the telephone jack. Plug in a different telephone. If you still hear other calls, the problem is probably in the wiring or local service. Call your local telephone company.

Caller ID is a subscription service. You must subscribe to this service from your local telephone company for this feature to work on your telephone.

The caller may not be calling from an area which supports caller ID.

Both you and the caller's telephone companies must use equipment which are compatible with caller ID service.

If you subscribe to DSL service, install a noise filter to the telephone line between the telephone base and the telephone line jack. Contact your DSL service provider for filter information.
