Control your computer-enabled TV from the comfort of your couch without the need for a mouse. The K400 Plus Wireless Touch TV Keyboard allows you to navigate seamlessly with its built-in trackpad. The keyboard enables you to work wirelessly up to a range of 10 m or 33 ft without having to move around. It’s large enough for most family dens and living rooms. The K400 has media-friendly controls and a familiar key layout so you can easily navigate without the hassle of a regular remote control. Forget complex setup procedures. Connect the K400 to your computer or TV with a single wireless connection using the Logitech Unifying receiver. Plug it into the USB port, and you’re ready to go. The Unifying receiver also allows you to connect multiple Logitech devices at the same time. There’s no need for continuous charging with the K400’s 18-month battery life. You can use the keyboard for longer without worrying about replacing batteries. When it’s time to replace them, you quickly pop in 2 more AA batteries, and you’re ready to go again.
