      If you cannot hear a dial tone on your Panasonic Cordless Telephone, ensure that you are using the supplied telephone line cord, as your old telephone line cord may have a different wiring configuration. Check that the base unit’s AC adaptor or telephone line cord is properly connected. If the issue persists, disconnect the base unit from the telephone line and connect the line to a known working telephone. If the working telephone operates properly, contact our service personnel to have the unit repaired. If the working telephone does not operate properly, contact your phone service provider.
