Troubleshooting

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

Other electronic products can cause interference to your cordless phone. Try installing your phone as far away from the following electronic devices as possible: television sets, VCRs, or other cordless telephones.

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 your phone is plugged in with a modem or a 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 phone to a higher location. The phone will likely 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).

service. Call your local telephone company.

My cordless handset does not ring when I receive a call

Make sure that the ringer is not turned off. Refer to the section(s) on ringer selection in this user’s manual.

Make sure the telephone line cord is plugged securely into the telephone base and the telephone jack. Make sure the power cord is securely plugged in.

The cordless handset may be too far from the telephone base.
