<p><P>PROBLEM TO BE SOLVED: To solve a problem that an output from an LC resonance circuit of an electronic apparatus is susceptible to an influence of a temperature. <P>SOLUTION: The electronic apparatus that has the LC resonance circuit and a micro computer is calibrated based on a signal output from the micro computer to the LC resonance circuit and a signal output based on a variable capacity element of the LC resonance circuit so that an output from the LC resonance circuit becomes a maximum level irrespective of the temperature. The calibration is conducted periodically. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
