Troubleshooting

You may have too many extension phones on your telephone line to allow all of them to ring simultaneously. Try unplugging some of the other phones.

The layout of your home or office might be limiting the operating range. Try moving the telephone base to another location, preferably on an upper floor.

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).

Test a working phone at the phone jack. If another phone has the same problem, the problem is the phone jack. Contact your local telephone company (charges may apply).

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

Re-install the battery, and place cordless handset in the telephone base. Wait for the cordless handset to re-establish its connection with the telephone base. Allow up to one minute for this to take place.

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