Dialog / silent mode setting means works, and if the mute button 30 is pressed on the caller base unit in the standby mode, the dialogue / speech mode setting means for setting the voice-speaking mode that allows only the transmission is provided. It comes to work.
Therefore, if the mute button 30 is not pressed, when the room call operation (G) is performed between the room base unit 2 and the extension base unit 3 using the channel selection switch or the like between the room base unit 2 and the extension base unit 3, it is called. The additional base unit 3 is notified of the ringing tone and connected to the communication circuit with the room base unit 2 that has performed the call (H).
The same operation is performed when the extension master 3 calls the room master 2 or when the extension masters 3 and 3 call each other.

If the dialogue / silence mode setting means (I) is activated on the called master side, the called master side cannot respond because of the silence mode, but the mute button 30 is pressed while the telephone line is connected. By pressing the button, the mute mode is changed to the interactive mode (E), and a two-way call can be made possible.
The dialogue / silence mode setting means is useful when there is a sudden unexpected call during a conversation .
When the loudspeaker mode (J) is set by the dialogue / speech mode setting means (I) on the caller base unit, no response can be made from the called base unit.

In this intercom system, when a call operation is performed from the front door 1, a call signal is sent from the back room 2 and the extension base 3 in the same manner as the operation of the front door 1 and the back room 2. Detected (hereinafter, the operation of the extension master unit is omitted), a ringing sound is emitted from the speaker 24, and power is supplied from the power supply circuit (not shown) to the camera 14 of the front door unit 1, whereby the video is monitored 22 (Not detailed).

When this call is confirmed and a dialogue operation (C) is performed, a telephone line is connected between the entrance cordless handset 1 and the living room master 2 in the dialogue mode.
If the mute mode is set at this time, it goes without saying that the setting is canceled.
Therefore, when the solicitation of some kind is called from the entrance cordless handset and the corresponding resident wants to talk only with another resident, when the mute button 30 is pressed, the CPU 29 detecting this controls the call circuit 23. Then, the setting is changed to the mute mode so that the sound input from the microphone 25 is not reported from the speaker 12 of the front door 1.
In addition, when the call termination operation (F) is performed, a function for storing the state before the call operation is performed and automatically restoring the state is also provided.

As described above, the mute button 30 combines the physical operation of the mute means, the dialogue / silence mode setting means, and the dialogue / speech mode setting means , so there is no need to provide a dedicated button for function setting.
The physical operation means used for the mute means ( dialog / silence mode setting means and dialogue / speech mode setting means ) is not only the operation of pressing the button switch, but also the operation of continuously pressing the button, the operation of switching the slide switch, the touch panel The contact operation etc. can be mentioned.
In addition, the notifying means for notifying that the mute mode is set can display not only the lighting and blinking of the LED, but also display an icon or a message on the monitor, or can be notified by voice.
