徴とするインターホン。A telephone that has a transmission line connected to the other party's telephone is connected to a telephone circuit that allows a telephone call to be made via the transmission line, and a power supply circuit that supplies power to the telephone circuit. In the intercom equipped with a battery, the telephone set is equipped with a display circuit, and
The display circuit is connected to the power supply circuit so as to be able to detect the voltage of the battery, and if the voltage of the battery is higher than the recommended battery replacement voltage, the display circuit continuously lights up a light emitting element to be described later, and detects the voltage. When the voltage is lower than the recommended battery replacement voltage and higher than the call-disabled warning voltage, a light-emitting element (described below) is made to blink, and when the voltage falls below the call-disabled warning voltage, the light-emitting element (described below) is turned off. Does it consist of a circuit and a light-emitting element connected to the control circuit so that it turns on, flashes, and turns off continuously in response to the control circuit?
A special intercom.
