With upgrades from Windows 7 to Windows 10, or larger packages of Windows Updates, it is often reported that the Bluetooth connection to the computer and the NOAHlink will need to be reestablished. If you cannot locate the NOAHlink thru the fitting software or NOAHlink Properties after a Windows update, first try to just unplug and replug the Bluetooth adapter, if that is not successful then remove and re add the NOAHlink thru Devices and Printers.
