The third decoding means decodes the output header signal into the first original header signal and the first check signal while the guessing clock code is substantially the same as the clock code. The isolation trench and spaces are filled with a dielectric material. The device includes structure for securing the anti-theft device to the periphery of the cabinet, structure for preventing the anti-theft device from being laterally and vertically removed from the cabinet, and a releasable assembly for selectively allowing and preventing access to the interior of the cabinet through the door.
