Abstract

A programmable remote control automatically learns characteristics necessary to generate an appliance activation signal. A sensor is positioned proximate to the appliance. A sequence of different activation signals is transmitted. A determination as to which signal activated the appliance is made based on a received sensor signal. Data representing the determined activation scheme is associated with an activation input.
