Mobile radio telephone

Abstract

Abstract The invention is based on the object of developing a known mobile radio telephone in such a manner that data losses due to unintentional operation of operating and input elements, particularly by switching- off the radio telephone, are avoided. The object is achieved by the fact that a switching-off command by the microprocessor circuit (25) of the radio telephone (10) is only executed and that the mobile memory (18) can only be taken from the handset (11) when the following conditions are met. There must be no conversation taking place and all settings existing before the switching-off must have been transferred in the form of data into the mobile memory. During the later insertion of the mobile memory, the data stored in it are then transferred into a main memory (26) of the microprocessor circuit (25). The drawing shows a handset in perspective view and a radio transmitting and receiving set (12) connected thereto. <IMAGE>
