<p>The checking process involves using a data transmission unit (B) with an aerial (A) to transmit information (BT) via a signal path. A receiving device (AP) receives this information. The end coded signals go to a logic control unit (KE) which compares them with a code and can be set in accordance with the operating state of the data transmission unit and/or the signal path.</p> |
