††A remote control is a device which can 'instruct' electronic devices, such as televisions, video recorders and stereos from a distance. When a button is pressed, the battery-powered controller emits an infra-red signal which can travel from one side of a room to the other, so long as there are no objects interrupting its path.
The relevant machine receives the signal and translates it into a particular instruction, operating as the user intended.
