The hand-held unit is the transmitter. The receiver is built into the opener's drive box. The typical openers of a couple of decades ago used "DIP switches" ( http://en.wikipedia.org/wiki/DIP_switch ) to set a code. The remote and the drive had to have the same code or the door wouldn't open. An 8-pole DIP switch has 256 possible codes to minimize the chance of your inadvertently opening your neighbor's garage door or vice versa (if you had the same opener).
