Abstract
A universal remote control interacts with a user to assist in training to one or more appliances. If the appliance is activated by a rolling code activation signal, a sequence of different rolling code activation signals is transmitted until the user indicates a successful transmission. If the appliance is activated by a fixed code activation signal, a fixed code word is used to generate and transmit each of a sequence of different fixed code activation signals until the user indicates a successful transmission. At least one of the sequences of activation signals inserts a preset amount of time after each activation signal transmission. If user input is not received within the preset amount of time, the next activation signal in the sequence is transmitted.
