If your F-keys aren't working as programmed, the problem is most likely with the configuration. You can check and change your F-key settings in the Logitech SetPoint Mouse and Keyboard Software.

To check or change your F-key assignments:

1. Launch the Logitech SetPoint Mouse and Keyboard Software.

   NOTE: If you don't have SetPoint installed, you can download it from the Illuminated Keyboard Downloads Page.

   Start > Programs > Logitech > Mouse and Keyboard > Mouse and Keyboard Settings

2. Once SetPoint opens, click the My Keyboard tab at the top of the SetPoint Settings window.

   NOTE: If you have more than one Logitech keyboard and the Illuminated Keyboard isn't currently displayed, click the down-arrow icon next to the current product name and select it from the drop-down menu that displays.

3. Click the "F" icon on the left toolbar to display the F Key Settings screen

   

4. In the Select F Key field, choose the function key you want to check or change.

   NOTE: The pictures in the list match those shown above the numbers on the function keys. For example: My Home is F1.

   

5. In the Select Task list, choose the task you want to assign to the chosen function key.

   NOTE: You can click the "?" icon by F Key Settings at the top for detailed descriptions of these options.

   

6. Click Apply to save your settings and then OK to close SetPoint.

If you prefer, you can make these programmed functions happen without having to hold down the FN key when you press an F-key. (Instead, you'll have to hold down the FN key for the default F-key functions.) To make this change, select the Swap F key functions check box under the Select F Key field shown above.
