The 90 Series remote control (with yellow battery test light) works only with door openers and light controls having an orange "Smart" button and a yellow indicator light. The code between the remote control and the receiver changes with each use, randomly accessing over 100 billion new codes.

Programming instructions are described and illustrated below.
