Abstract (en)
The device has a portable electronic box and an automatic electronic control circuit communicating with each other by radio waves. The box and the circuit have communication circuits having processors, respectively, that implement two different signal modulation modes and modulate input signals with the modes. The processors (300, 305) use a same carrier wave and a transmission/reception antenna. The control circuit`s processors verify coherence of signals received according to the modes to allow starting of a motor of a mechanical lift if the coherence is verified.
