ABSTRACT:
A kit for converting to cordless operation a telephone having a corded handset and a base unit, the base unit having a handset connector jack and a handset receiving cradle for matingly cradling the handset and the corded handset having a housing, a microphone, a speaker, and a cord for electrically connecting the handset to the handset jack. The kit includes a module having a fastener for fixing the module in mating engagement with the base unit and a connector for electrically connecting the module to the handset jack. An uncorded handset mating with the handset receiving cradle is provided, the uncorded handset having a housing generally matching that of the corded handset. The module and uncorded handset exchange signals via radio transmitters and receivers and contain switches responsive to cradling and uncradling of the uncorded handset so that the converted telephone operates as if the uncorded handset remained connected by a handset cord to the base, while the overall shape and configuration of the telephone is preserved.
