<p>When a predetermined time has elapsed after a control signal is received from a device control unit, a direction search unit instructs a microwave transmission unit to transmit a microwave and then instructs the microwave transmission unit to scan a microwave. When a communication signal reception unit has received a report signal from a remote controller, the direction search unit instructs the microwave transmission unit to stop scan of the microwave. After this, the direction search unit instructs a power control unit to increase the power level of the microwave. Moreover, the direction search unit judges whether the communication signal reception unit periodically receives a charge-in-progress signal indicating that charge is in progress from a communication signal transmission unit of the remote controller and whether the communication signal reception unit has received a charge completion signal indicating that the charge is completed from the communication signal transmission unit.</p> |
