Abstract: A call box apparatus includes a controller unit, a radio frequency audio transceiver unit controlled by the controller unit, and a sensor assembly connected to the controller unit for controlling operation of the controller unit. A power supply assembly, an audio storage assembly, an output speaker unit, and an input microphone unit are connected to the controller unit. A housing assembly houses the controller unit, the radio frequency audio transceiver unit, the sensor assembly, the power supply assembly, the audio storage assembly, the output speaker unit, and the input microphone unit. The housing assembly includes a hinged door. The housing assembly includes a first housing portion which supports the door, and a second housing portion which supports the first housing portion. The door includes a door lock assembly. The sensor assembly includes an open-door sensor and a key-operated switch assembly. The power supply assembly includes a rechargeable battery. A solar panel assembly and a power supply interface assembly are connected to the rechargeable battery and the solar panel assembly. When the door is opened, an automatic sequence takes place. Power is applied to the radio frequency audio transceiver unit and all logic circuits. The radio transmits an alarm tone (warble) and a voice message identifying the call box apparatus. A second voice message emanates from the output speaker unit to deliver user instructions. At this point, the call box apparatus becomes a two-way radio station.
