Through a microcontroller, control signals are transferred to a transmitting and receiving unit or configuration data are transferred. Through the transmitting and receiving unit, in a first operating state transmission signals are issued, while controlling the control signals of the microcontroller. Upon a first specified event, the transmitting and receiving unit is switched to a second operating state through a one-time transfer of corresponding configuration data by the microcontroller. In the second operating state, the transmitting and receiving unit automatically transmits repeated transmission signals. The microcontroller immediately switches to a current-saving or non-current, inactive operating state after said microcontroller has switched the transmitting and receiving unit to the second operating state. As a reaction to a second specific event, the transmitting and receiving unit switches to the first operating state and produces a state change signal for the microcontroller, which switches to the active operating state as a reaction thereto. |
