Just the way you want it

Your keyboard isn’t just for typing. Many can launch Web pages and applications, control your media, and sometimes even show you what song is playing.

With Logitech® SetPoint™ software, you can not only change the function of your keys—you can customize all sorts of things to make your keyboard work better for you.

Hot keys at your service

Is that hot key not so hot in your eyes? You can easily change what it does with SetPoint. You simply select your keyboard, find the hot key you want to change, and pick what you want it to do.

So you can make that unloved button open a Web page, launch your favorite program, open a file or folder, and more. Or you can assign keystrokes to it.

F-keys that function your way

You don’t have to let your F-keys push you around either. You can program them to do what you want, too. You just choose the Function Key tab and make your changes.

Blocking the lock keys

No need to fear that Caps Lock key. SetPoint lets you disable the keys you’re afraid to accidentally hit—like all those lock keys, the Insert key, and the Windows® Start key.

Battery check-up

Keeping an eye on your battery level is easy—the Battery tab lets you see how much juice you’ve got left so you’ll never be left powerless.

Making special features more special

Whether your keyboard’s got zoom buttons, an LCD, a TouchDisc, or Media Pad, SetPoint lets you set things up the way you like them. You can speed up or slow down your zoom. Tell your LCD not to bug you with message alerts when you’re listening to music. Change the pointer speed on your TouchDisc. And much more.

More power to you

No one likes to run out of batteries. It’s a hassle. Scouring the house for new ones. Finding two that still have juice. Even making an extra trip to the store. At Logitech, we’re doing everything we can to make the hassle of replacing batteries hassle-free.

Batteries? What batteries?

Wireless keyboards let you avoid the inconvenience of cords. But unlike a corded keyboard (which is powered via USB and your computer), wireless keyboards use batteries, and batteries do run out of power.

Don’t even want to think about changing batteries? We’ve got just what you need. You can choose a keyboard with a battery life of 15 months—or even three years—and practically eliminate the hassle and expense of changing batteries.*

You can control your computer from across the room. And be more productive and comfortable on the go. Logitech wireless keyboards give you the freedom to do more, in more places—without the clutter of cords. From basic to Bluetooth, we’ve got plenty of options to choose from. But don’t worry—we’re here to untangle all the terminology and technology.

The power player: Advanced 2.4 GHz

For the best-of-the-best wireless connection, Logitech® Advanced 2.4 GHz wireless gives you the reliability of a cord with cordless convenience and freedom. Advanced 2.4 GHz wireless virtually eliminates delays and dropouts—even in the busiest wireless environments, such as a high-tech office.

In addition, Advanced 2.4 GHz wireless is designed to optimize battery power. (Many of our keyboards with Advanced 2.4 GHz wireless can offer up to three years of battery life.)

Your keyboard is automatically paired with your computer. So, you can use your keyboard with the most demanding applications and know that every keystroke you make will be carried out instantaneously. It uses less battery power than other wireless technologies, too

Fast and reliable: 2.4 GHz

The predecessor to Advanced 2.4 GHz wireless, our basic 2.4 GHz wireless keyboards deliver wireless convenience you can count on.

Thanks to its ability to transmit data in two directions, your keyboard can save power by turning itself off when your PC is dormant. Your keyboard can even sense if there’s wireless interference and change channels to establish the most secure connection.

Have a look at all 2.4 GHz wireless keyboards.

Back to basics: 27 MHz RF

An older favourite, you can use 27 MHz RF up to six feet away from your computer.

It uses less battery power than devices that operate on higher-frequency bands. And it can keep a secret too—advanced encryption securely transmits your keyboard strokes to the computer.
