Abstract

Abstract A conversion kit, consisting of a two piece adaptor set, allows a conventional non-cordless telephone to be converted to a cordless telephone. Each piece consists of a unitary body which houses a transmitter/receiver therein and a conventional modular male telephone plug. To convert a standard non-cordless telephone to a cordless telephone, the telephone cord is removed and one of the transmitter/receivers is plugged into the socket on the telephone base and the other into the corresponding cord socket on the handset.
