るコードレス電話装置。 It consists of a base unit equipped with a transceiver connected to a telephone line, and a slave unit that is connected to the base unit wirelessly.The slave unit is connected to an outside line via the base unit, and a switch connects the base unit and In a cordless telephone device equipped with an intercom function that allows communication between a parent and child by separating the phone, a first tone signal generator generates a first tone signal of a low frequency outside the voice signal band when a call switch is closed to the handset. and a second tone signal generator that generates a second tone signal of a high frequency outside the audio signal band by dialing or calling the base unit, while the base unit detects the first and second tone signals. means for amplifying the second tone signal, means for connecting a telephone line by generating an output of the first tone signal detection circuit, and the first and second tone signal detection circuits. 1. A cordless telephone device comprising means for transmitting a dial signal upon output generation, and means for supplying a second tone signal to the amplification means when only a second tone signal is detected.
