Embodiment Construction
[0029] according to figure 1 A device 1 , 2 according to the invention shown in FIG. 2 , eg a terminal device 1 or a portable part or a station device 2 or a stationary part, contains a circuit 20 .
[0030] Circuitry 20 includes transceiver 9 coupled to an antenna. The control input of the transceiver 9 is coupled to the output of the selector 4, the control input / output of the transceiver 9 is coupled to the control input / output of the processor system 10 by a link. The processor system 10 includes, for example, a processor and a memory. A first input of the selector 4 is coupled to a first field 12 of a memory 11 for storing a first (longer) sequence of frequencies. A second input of the selector 4 is coupled to a second field 13 of the memory 11 for storing a second (shorter) frequency sequence. The first and second fields 12 and 13 are further coupled to the output of a counter 14 . A control input of counter 14 is coupled to a control output of processor system 10 . ...
