A:AnswerDid you try the small on/off switch on the right side toward the back of the keyboard? I only ask because I did not know it was there and had problems with mine at first. I actually took one back and exchanged it because it would not connect. Now I think it was likely turned off and I didn’t know it.
A:AnswerThey are used to connect it to different devices. After assigning it to up to three devices, pressing a number connects it to the device assigned to the number pressed (and disconnects it from the device it was connected to).
A:AnswerYes. It is not obvious though. The key is in the usual spot but it says "Start" instead of the windows symbol. It is also a Function key so depending on your Fn Lock setting the key might be in another mode.
If the default settings got changed, with or without knowing, that prevents you from using default function keys (F1 thorough F12), which I need to use a lot, without keeping FN key pressed every time, you can change it by pressing FN + ESC key combination once to LOCK it. This way you don't have to use two fingers (eg. FN + F12) when there is a need to use one of the F1 - F12 keys.
Hope this helps someone!
A:AnswerThis Keyboard & Mouse (MK850), and other recent Logitech "Multi-Device" Mice or Keyboards, can be connected via additional USB (Unifying Receivers), to three (3) computers or devices with USB connectors - you just need to purchase additional "Unifying Receivers" and download the "Unifying Software" from Logitech, that allows for pairing and un-pairing of devices.
Bluetooth connections are available, but not required, if you choose USB connections via additional Unifying Receivers ($10 or under, each).
A:AnswerI would say that as far as noise this is on the quieter side. You can hear it but it's mostly on how hard you hit the keys. On a scale of 1 - 10 with 10 being very loud, I would put this as a 3 or 4 .
A:AnswerHi Colleen, yes you definitely can purchase another Unifying Receiver for your MK850 Combo. Here is the link to do so: https://www.logitech.com/en-us/products/mice/unifying-receiver-usb.910-005235.html?crid=7. It's very inexpensive to replace and all you'll need to do after receiving it, is download the Unifying Software which can be found here: https://support.logi.com/hc/en-us/articles/360023237854. Hope that helps!
A:AnswerYes, vi Bluetooth and dongle support in some versions. The dongle supports USB keyboard driven functions, so long as the BIOS supports it properly (many in the past were horrible with USB keyboards) it will work. Bluetooth functionality is always getting better in most Linux variants.
