Harmony 890 Advanced Universal Remote Reviewer's Guide - Page 4 2. Product Overview The Harmony 890 Advanced Universal Remote is Logitech's first retail remote to use radio frequency (RF) wireless technology, allowing people to control home-entertainment components hidden behind closed cabinets, or even those that are in other rooms of a house. The Harmony 890 remote offers the same ease of use and one-touch, activity-based control that has helped Harmony quickly become the most popular brand of advanced universal remotes in the U.S. marketplace - but by using a combination of infrared (IR) and RF wireless technologies, this remote offers a new level of flexibility and control in the home. The Logitech Harmony remote controls comprise the No. 1 selling brand of advanced programmable remotes in the U.S. Typically, the device-specific remote controls that ship with consumer electronics products work solely with infrared wireless signals - light waves that are easily blocked by furniture or walls. Using an IR remote, people must point the remote directly at the IR sensor on the components they want to control. If the component is behind a cabinet door, or if furniture or any other obstacle blocks the beam, the remote can't communicate with the device, and thus can't control it. The Harmony 890 remote communicates with Logitech's RF Wireless Extender, included in the retail package, by using RF signals. Unlike light waves, these radio waves can travel through solid objects - such as cabinets, doors, furniture, and walls. Located within range of the home-entertainment components that users want to control, the RF Wireless Extender receives the RF signals and then, based on this information, blasts out the necessary IR commands to control the components. It may sound complicated - after all, the technology is sophisticated. But using the Harmony 890 remote is easy. People don't need to worry about aiming the Harmony 890 remote at their entertainment systems, or opening up the cabinet doors to expose their components to receive infrared signals. And as with all Harmony remotes, pressing one button on the Harmony 890 remote puts the entire entertainment system in the right state to watch TV or movies, or listen to music - making it simple for any family member to enjoy the modern home-entertainment experience without frustration or guesswork.
