コードレス電話機。 In a cordless telephone consisting of a cradle part and a handle part, when the handle part is placed on the cradle part, the power supply of the cradle part is used to constantly operate the empty channel search circuit and the cradle part and the handle part are connected. A circuit that instantly secures an empty channel on a wireless line between departments, a calling circuit that generates a calling signal in response to an incoming call signal from the outside, and a circuit that sends an incoming call signal to the empty channel in response to the operation of the calling circuit. an intermittent reception circuit that intermittently detects the presence or absence of a call signal from the cradle unit using a power source within the handle unit when the handle unit is separated from the cradle unit; and an intermittent receiving circuit that detects the call signal. means comprising a circuit for later searching for an empty channel and securing an empty channel; a circuit for accepting a call signal from the cradle after the empty channel is secured; and a circuit for sending an incoming call signal from the cradle to the empty channel. A cordless telephone characterized by having.
