receivers having an purple “learn” button. The rolling code between these buttons and the receiver changes with each use, randomly accessing over 100 billion new codes.

As an added feature, the 4th push button is capable of learning or being trained to duplicate or match another CGI manufactured 315MHz fixed code remote. This feature is normally used when several remotes are required to operate one fixed code device such as a gate opener or commercial dock door. In this case, the code transmitted to the receiver remains constant or fixed, not using the Security✚
