ABSTRACT:
An electronic device able to accurately receive external wireless information, a reception controller for the electronic device, and a reception control program for the electronic device. A radio-controlled timepiece has a stepping motor unit and an external wireless information reception unit for receiving a carrier wave with time information. The stepping motor unit has a magnetic field evaluation unit for detecting whether or not an external magnetic field is present and outputting a signal indicative of whether or not such an external magnetic field is present. The external wireless information reception unit has an antenna for receiving external wireless information and a receiving circuit for processing external wireless information received from the antenna. A reception controller controls the external wireless information reception unit according to the external-magnetic-field-detection signal output from the magnetic field evaluation unit.
