Claims

[Claims for Utility Model Registration] (1) A timing circuit, a display unit, a control unit that reads the time signal output from the timing circuit and outputs it to the display unit, and a control unit that reads the time signal output from the timing circuit and outputs it to the display unit, and a time signal of the timing circuit through the control unit. A telephone comprising a key input unit for instructing correction, an incoming call detection circuit for detecting a ringing signal from a telephone line, and a ring tone generation circuit for generating a ring tone based on an output signal of the incoming call detection circuit, wherein the control unit includes: When the time read from the clock circuit matches the control time pre-stored in the memory in the control unit through the operation of the key input unit, the ringtone mode corresponds to the ring tone mode stored in the control unit together with the control time. A telephone set, characterized in that the volume and/or tone produced by the ring tone generation circuit is switched by a control signal. (2) Claim (1) characterized in that the ring tone mode stored in advance in the memory in the control unit together with the control time is generation and stop of the ring tone.
Phone listed. (3) The telephone set according to claim 1, wherein the ringtone mode stored in advance in the control section is a plurality of volume levels preset in the ringtone generation circuit. (4) A claim characterized in that the ringtone mode prestored in the control unit is a plurality of tones preset in the ringtone generation circuit.
(1) The telephone listed above.
