Abstract: In a method for operating a transponder (1, 41), the transponder (1, 4) receives a signal from a transmitter (2, 42). The signal comprises an information about a reference sensitivity and the transponder (1, 41) has an input sensitivity such that the transponder (1, 41) detects only signals above a certain power corresponding to the input sensitivity. In response to the received signal, the input sensitivity of the transponder (1, 41) is adjusted to the reference sensitivity.
