In order to control reliably a mobile receiver (2) in a transmission system working interruptedly with multiple stationary transmitters (S1...n), its reception standby is monitored by means of a continuous test signal (T1,2). A corresponding test transmitter (9, 10) is designed advantageously, as are all other normal transmitters (Sn), as a transponder, the energy signals (E) of which lie directly on its response level. Similarly, an interrogator is also operated advantageously as a receiver (2) directly on its response level during a non-interrupted on-line test using a test signal (T1,2). In addition to providing a reliable reception standby monitoring and error diagnosis, cross-talking is securely avoided thereby ensuring freedom of memory. 00000 |
