Abstract

A communication device includes a first receiver, a second receiver, a communication module, and a controller. The first receiver receives an operation signal from a remote controller. The second receiver receives a radio signal with a specific frequency. A power consumption of the second receiver is less than that of the first receiver. The communication module is capable of transmitting the operation signal to a first communication device. The controller controls power supply to the first receiver and the communication module and starts power supply to the first receiver and the communication module if the second receiver receives the radio signal. The communication module turns to a standby state if the first receiver does not receive the operation signal after start of power supply to the first receiver.
