Abstract
Provided is a portable communication device including a receiver, a transmitter, an adjustment signal generator, an adjustment signal detector, and a control circuit unit. The transmitter transmits an adjustment signal to the receiver in order to adjust a received resonant frequency. The adjustment signal detector detects a parameter including information on a transmission state of the adjustment signal at a time of transmitting the adjustment signal. Then, the control circuit unit corrects a deviation of the received resonant frequency based on a detection result of the adjustment signal detector.
