Abstract
A soil compacting machine has a receiver unit that can receive control signals from a transmitter unit to a receiver unit. The transmitter unit can be operated by a user and is separate from the machine. The control signals are then processed into commands and sent to a control mechanism of the machine. Signals originating from the transmitter unit and reflected by the machine are received as safety signals by a receiver connected to the transmitter unit and are tested in relation to at least one distance-dependent parameter. If the parameter which is tested shows that a predetermined safety distance between the machine and the receiver is not respected, the transmission of the control signals or the operation of the machine is interrupted.
