Abstract
Remote control commands are provided to an accessory device utilizing a radiotelephone, such as a cellular telephone, as a receiver which receives control commands over a wide area cellular network utilizing a remote control adaptor. The adaptor may take the form of a detachable adaptor attaching to the radiotelephone or a remote control battery pack replacing the normal battery pack for the radiotelephone or a docking station serving as a remote control as well as a battery charger for the radiotelephone. Alternatively, a lock box is provided allowing remote actuated access to a compartment of the lock box. The radiotelephone acts as a receiver providing an audio signal to a tone signal decoder which passes decoded and converted tone signals to a comparator which assembles a command for comparison to a predetermined password. Switches are activated responsive to the comparison to control accessory devices. Power may be provided by the switching circuit to accessory devices from the radiotelephone system bus, battery or from a separate power source. A user'"'"'s radiotelephone may thereby be converted on an as needed basis to operate as a receiver for remote control of accessory devices and readily return to normal use as a radiotelephone when remote control is no longer required.
