*** RF EXTENDER INCLUDED *** Control your entire home entertainment system with just one button. Effortlessly switch between watching home theater and listening to music, by selecting a single activity button. Colorful icons accompany text on the LCD screen to allow for quick and easy command of home-entertainment equipment and household appliances that may be out of range for a traditional infrared remote. Integrate up to 15 devices—including lighting and household appliances. Save energy! Each time a new activity is selected, the remote establishes the proper state of all of the components needed for the current activity, and turns off the components that are not needed. Set it up in a snap with an advanced setup wizard. The online setup also makes it easy to update a remote when upgrading your home-entertainment system. The Harmony setup wizard does the programming, so you don't have to. Just connect your remote to your computer and answer a few questions about how you currently use your home theater. Logitech's patented Smart State Technology® does the rest. Don't worry about using up batteries with the rechargeable lithium ion battery. Store the remote on the attractive charging station when not in use. Easily view and select. Color display icons and 8 on-screen activity buttons make it easy. Effortlessly switch between watching HDTV and listening to music, by selecting a single activity button.
