The RF Remote for Windows Vista is a sleek and powerful RF remote control designed specifically for use with Vista s Media Center multimedia software. It provides more range convenience and flexibility than infrared remotes. Unlike an infrared remote this RF remote does not require line of sight to the RF receiver. This allows you to manage Media Center from more areas within the room or even from other areas of your house. Since the RF signal works through walls and furniture you have more flexibility in locating the PC that will be used to run Media Center. For example you can place the PC inside an entertainment center cabinet or within an AV closet and still easily control Media Center with the remote.Remote ControlInput Device :  Keypad PC Compatibility :  Win Max Operating Distance :  90 feet Remote Control Technology :  Radio Supported Devices :  Personal computer Dimensions&MiscellaneousDepth :  1.30 Inch Height :  2.4 Inch Width :  7.90 Inch BatteryBattery Type :  AA Type Service&SupportService & Support Type :  1 year warranty Special FeatureRoHS :  Yes UNSPSC CodeUNSPSC Code :  43211600
