Universal remotes come in handy, because you can control numerous audio/video components with a single unit, without having multiple controls cluttering your coffee table. The 5-in-1 RF/IR Non-Learning Remote performs the same functions, and with its own X10 button, you can control your lights and appliances without having to be in the same room with them. This special home control feature works in conjunction with a wireless transceiver (sold separately) to communicate RF commands. Four AAA batteries are also required but sold separately. The 5-in-1 RF/IR Remote replaces up to five remotes to let you control practically everything electrical in your home. It has IR technology that lets you control your TV, VCR, Cable and Satelite, and X10 RF technology that lets you control lamps and appliances anywhere in your home, so that within minutes, you can be using this remote to dim the lights, start brewing a fresh pot of coffee, and play your favorite movie. 100918-04
