Abstract
PURPOSE:To use a handset while being disconnected from a telephone set main body by inserting the radio set main body between the handset and the telephone set main body and incorporating a radio set also into the handset. CONSTITUTION:There are two connection modes between the telephone set main body A and the handset C, and when the handset C and the radio set main body B are connected by a cord, the radio set main body B is not operated at all but connected directly and the set acts like a conventional telephone set. On the other hand, when the handset C is not connected by the cord from the radio set main body B, the handset C and the radio set main body B are coupled by the radio system and a telephone user can communicate while being moved freely in the operating range of the radio transmitter-receiver.
