SYSTEM OVERVIEW The transmitter key consists of the fork (fork-shaped plastic component with a steel shank and the slide-in module with a hole for the key ring, and three buttons). The shank location is described below as "front", and the side of the slide-in module which contains the buttons, is described as
"top". The key ring hole is thus located on the back on the left. General functions of the buttons Whenever a button is actuated, a telegram is emitted containing the information as to which button has been actuated. Two successive button actuations are only recognized if they are effected with an interval of at least 65 ms. However, each button actuation gives rise to at least four successive telegrams, even if another button is being actuated while they are emitted. If the button is not released, max. 50 identical telegrams are emitted. If the button is released after more than 4 telegrams have been emitted, the telegram being generated is emitted, then the function is aborted. Each new button actuation results in a new computation of the alternate code, and in a new telegram sequence being sent. The control unit receives the various telegrams generated by button actuation, and is capable of distinguishing, via the alternate code, between continued actuation and several separate, successive actuations of the button.
