Radio system with generator and auxiliary storage

The radio system has a transmitter transmitting a radio signal and a receiver receiving the radio signal. The transmitter is assigned a generator (1) such that the transmitter is operated in an energy self-sufficient manner independent of a commercial power supply. The transmitter is arranged as transceiver and is adjusted on the receiver enabling the installation of a bi-directional radio communication in such a way that the reception of the radio signal-supported diagnostic data is transmittable to the transmitter from the receiver. An energy storage (2) is attached to the transmitter.
