The Dell Wireless Keyboard and Mouse (model number KM636) has two versions. Both are the same in appearance with an exception being the pairing feature which is either Logitech Unifying or Dell Universal. Confusion can occur because of identical appearances of the two versions, leading to improper pairing and non-functional devices. ResolutionHow to Verify Logitech Unifying v Dell Universal feature The easiest way to check the version and subsequent compatibility is to look at the logo on the USB receiver and compare that to the logo on the bottom of the keyboard and/or mouse. The Dell Universal logo comes with "BLUE RING" whereas the Logitech Unifying logo is an "ORANGE STAR."
Dell Universal devices (Keyboard, Mouse, and Dongle) are NOT compatible with any of Logitech Unifying devices (Keyboard, Mouse, and Dongle).
There are cases where these Unifying and Universal devices have been mixed up in use and this leads to devices not functioning. If this happens, check all the devices again to ensure that all devices are of the same Dell Universal or Logitech Unifying pairing. Once the pairing matches, you may have to resync your devices: NOTE: Dell Wireless Keyboard and Mouse (KM636) uses RF2.4Ghz wireless technology. It is NOT Bluetooth. There is no pairing button on the device and it needs the dongle + the software to resync. Affected Products Dell Wireless Keyboard and Mouse- KM636 (black) (责任编辑：) |
