The method involves adjusting and changing capacitance of a receiver circuit by switching-on or switching-off a set of capacitance values by using a control circuit that is supplied with electric current, such that a request signal received by a transponder receives a maximum voltage value. A middle or predetermined capacitance value is selected (S1) as a starting value, and the starting value is changed around one of the capacitance values. Another capacitance value is switched-on or switched-off based on increasing or decreasing of the voltage value. |
