Troubleshooting

•Eliminate any background noise. Noise from a television, radio or other appliances might cause the telephone to not dial out properly. If you cannot eliminate the background noise, first try muting the corded handset before dialing, or dialing from another room with less background noise.

•If other telephones in your building are having the same problem, contact your telephone service provider (charges might apply).

I hear other calls while using my telephone.

•Disconnect the telephone base from the telephone jack, and plug in a different telephone. If you still hear other calls, call your telephone service provider.

My telephone does not ring when I receive a call.

•Make sure that the ringer is not turned off (see Ringer volume on page 15).

•Make sure you plug in the telephone line cord securely into the telephone base and the telephone jack. Make sure you plug in the power cord securely.

•There might be too many extension telephones on the telephone line to allow all of them to ring simultaneously. Try unplugging one telephone at a time until the telephones start ringing.

•If other telephones in your building are having the same problem, contact your telephone service provider (charges might apply).

•Test a working telephone at the telephone jack. If another telephone has the same problem, contact your telephone service provider (charges might apply).

•Your telephone line cord might be malfunctioning. Try installing a new telephone line cord.

My calls cut in and out while I’m using my corded handset.

•If you are using the handset when this problem occurs, try unplugging the coiled handset cord and firmly plugging it in the handset and telephone base again.

•If you are using the headset, try unplugging it and firmly plugging it in again.

•If you are using the speakerphone, eliminate any background noise. Noise from a television, radio, or other appliances might cause the speakerphone to cut in and out. Try pressing MUTE when you are not speaking to eliminate the background noise.

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