Your Unifying receiver can be paired with up to six Unifying devices at a time. If you need to unpair a device for any reason, you can use Logitech Unifying software.  If you don't already have it installed, you can download Unifying software from the Software Downloads page.

NOTE: Before proceeding, please make sure you have either a wired mouse connected to the computer, or a second mouse connected to the receiver.

To unpair your device:

1. Open the Unifying software:
   Start > All Programs > Logitech > Unifying > Logitech Unifying Software
2. On the Welcome window, click Advanced…

   

3. In the left pane, select the device you wish to unpair.
4. On the right side of the window, click Un-pair, and then click Close. This will remove your mouse or keyboard from the list of Unifying devices and it will no longer work with your computer.

   

5. To make your device work again, you will need to re-pair it with the Unifying receiver. See Connecting a device to a Unifying receiver for more information.
