2.4 GHz, Touchpad, Black/White

10-meter (33 feet) wireless range
You can turn up the volume of a YouTube video, pause your vacation slideshow or tweet about the movie you just downloaded—all without getting up from the couch.

Large 3.5-inch, built-in touchpad
A large 3.5-inch, built-in touchpad makes vertical and horizontal scrolling intuitive. And multi-touch navigation makes it easier than ever to point and scroll your way through the Web.

Plug-and-play simplicity
Setup couldn’t be easier—you simply plug the tiny wireless receiver into a USB port and enjoy. Even the hot keys work right out of the box without software.

Logitech Unifying receiver
The tiny receiver stays in your laptop. Plus, you can easily add a compatible wireless mouse, keyboard or number pad—without the hassle of multiple USB receivers.

Comfortable, quiet typing
Whether you’re surfing the Web or e-mailing a friend, typing is just plain easy with sleek, low-profile keys that feel good and barely make a sound.

12-month battery life
You can go a full year doing the things you love without battery hassles. An on/off switch helps you save power when you’re not using the keyboard.

Advanced 2.4 GHz wireless
So you can work or play in more places—like your comfy couch—the long-range wireless connection virtually eliminates delays, dropouts and interference.

128-bit AES encryption
It helps protect your information by encrypting data transfer between the keyboard and receiver with one of the highest levels of data encryption available.

Easy-to-read keys
The bold, bright white characters make the keys easier to read in your living room.

Sleek and compact design
It saves space without compromising on comfort—and looks good, too, thanks to the clean lines and a touch of color and pattern on the touchpad.

Media hot keys
Mute, volume up, volume down and a Home button help you do the things you do most—instantly.

Vertical storage
The keyboard stands vertically for easy storage when living room space is limited.
