In order to control automatic working devices, especially soil compacting devices, a remote control device is provided which comprises a transmitter unit which can be actuated by a user and which is used to transmit control signals in the form of electromagnetic radiation and a receiver unit which is arranged on the working device and which outputs the received control signals in the form of electric control commands to the control unit of a working device. During operation of the working device, the transmitter unit can be connected to an external power source, which is arranged on the working device, via a cable for the supply of power thereto.
