The MK540 Advanced Keyboard and Mouse Set prioritizes user comfort, precision, and reliability. The full-sized keyboard is splash-proof and features keys with familiar size, shape, and texture. The ergonomically curved, ambidextrous mouse is specifically designed to remain comfortable even during long workdays. Both devices connect wirelessly via the included Unifying USB receiver, occupying only a single USB port. A single set of batteries lasts up to 36 months for the keyboard and up to 18 months for the mouse.

Enjoy ample freedom of movement without the hassle of tangled cables: USB wireless input devices establish a wireless connection to the receiver, which you plug into an available USB port.

This mouse and keyboard set supports Logitech Unifying technology. This means you can pair not only this mouse and keyboard but also up to six Unifying-compatible devices with the same receiver. This way, you keep your computer's USB ports free for other uses. Another advantage is that you can easily connect the input devices with a Unifying receiver if you've lost your old one.
