The IBM Enhanced Performance Wireless Keyboard and Optical Mouse use a 2.4 GHz R/F technology that does not interfere with Bluetooth or Wireless LANs. This product offers a 10-meter range. You can use it in large conference rooms together with a projector and in many other environments. Another benefit of this product is its ease of use. Unlike other wireless products that demand extensive setup, the IBM Enhanced Performance Wireless Keyboard only requires a driver install to begin operating. This keyboard has the same layout as the IBM Enhanced Performance USB Keyboard, which allows you to complete your computing tasks faster, more efficiently, and comfortably. Seven reprogrammable hot keys open programs, documents, and Web sites. The keys are set at the factory with Lock Desktop, My Documents, Word Processor, Spreadsheet, Calculator, e-mail, and Internet. To reprogram the hot keys, a software utility is included that lets you print a custom legend for the hot keys. A multimedia pod is included on the keyboard so you can easily control audio and video files, or launch your favorite media player. Microsoft Windows shortcuts are highlighted on the front skirt (front surface) of keys to help you perform tasks more efficiently. The keyboard also includes a detachable wrist rest with a smooth rubberized coating and a three-way keyboard tilt adjustment. Also included is an Access IBM key, which gives you easy access to on-system and online information (requires Internet access, not included) from IBM. Also included in this kit is an optical wheel mouse that uses 2.4 GHz R/F technology. To use this keyboard and mouse with your ThinkPad when you travel, use the small USB dongle and the mouse.
