Claims

[Scope of utility model registration request]

A base device connected to the subscriber telephone via a telephone line and having a transmitting/receiving circuit, and a handset having the transmitting/receiving circuit and wirelessly coupled to the base device and capable of communicating with the subscriber telephone via the base device. A telephone device comprising: a demodulation circuit that demodulates a code signal modulated with a carrier wave output from the other; and a pilot signal detection circuit that detects a code signal in the pilot signal. , a code matching circuit that controls transmission and reception between the base device and the handset depending on whether or not the code creed and the preset aid signal match; and a code matching circuit that controls the audio signal sent via the other transmission circuit. A telephone device comprising: a mute circuit; and mute circuit control means for detecting the output level of the demodulation circuit and controlling the mute circuit.
