A communication set-up having an electronic circuit; the circuit including at least one communication unit for wireless communication. The communication unit includes an antenna network connected to an antenna; and also includes an actuating unit. The circuit of the communication set-up further includes a signal processing unit, and in response to operation of the actuating unit, the actuating unit is configured to release a signal to the signal processing unit, which, on the basis of this, converts the communication set-up from a blocked state to an enabled state, or vice versa. In addition, a method for controlling such a communication set-up is described.
