A method of operating a communications receiver. The device includes a first lever supporting body arranged on a first side of a drum center and being movable in an axial direction. In the method, a reference timing number is stored, representing the predetermined time in periods of the predetermined input bit frequency. The electromagnetic pulse interacts with the working surface causing an indentation to form. A placement script may then be automatically executed that, for example, places the text of each suggestion on the target page. The first and second circuitry being operated to change state at the same time so as to hinder optical detection of the light emitted by the first circuitry.
