The K950 Signature Slim is not compatible with the Unifying Receiver. This keyboard only uses Logi Bolt or Bluetooth 5.1 for connection and therefore cannot be used with your existing Unifying setup.
Since your MX Master 2S mice and K850 keyboard are not compatible with the Bolt Receiver, the K950 Signature Slim would unfortunately not fit into your current setup. You would either have to carry an additional Bolt Receiver in your notebook or switch to another solution.
Hello, to lock the FN key on this keyboard, you need to press the FN + Escape keys simultaneously. This switches between the multimedia keys and the function keys. A notification is displayed to indicate the change of mode. By default, the keyboard uses the multimedia keys for direct access.
There is a user manual for this keyboard, including these instructions, available online in Logitech's official documentation and in the user guides for the Signature Slim MK950 keyboard and mouse combo.
Yes, they are printed on mine. I'm generally very happy with the keyboard, it's comfortable and has lasted a long time without any visible or noticeable wear.
The keyboard uses two AAA batteries for power, which are non-rechargeable alkaline batteries included with the product. It does not have a built-in rechargeable battery or support charging via cable. Therefore, you cannot use rechargeable batteries that charge inside the keyboard, but you can use standard AAA rechargeable batteries if you replace them manually. The keyboard is designed to operate with replaceable AAA batteries only. Battery life is estimated at around 36 months with alkaline batteries.
