Logitech's Harmony 890 remote control uses both radio frequency (RF) and Infrared (IR) wireless signals to deliver powerful complete control of your home-entertainment system that may be hidden behind cabinets. With a wireless range of up to 100 feet, the Harmony 890 remote sends RF commands to a wireless receiver, which then blasts infrared signals to the components. The Harmony 890 remote makes universal control for home entertainment and advanced lighting systems simple.
