After some fears, not seeing the keyboard work on my PC (it complements my usual keyboard because it takes hardly any room between my notepad - yes paper, it still exists !! - and stacks of books - yes, with real paper with ink), I took the time to understand the blockages. First, the driver could not be installed (but with patience, it finally arrives): The Bluetooth USB key provided was redundant with another key addition I had already installed. Here's how to lose a little time! By cons, this key (housed in the keyboard when not in use) may be useful for devices that have none. Then the keyboard is not automatically detected. You must go to "Add Bluetooth Device" (in W7). A final concern for the pairing to occur, we must return an encrypted code, proposed by W7: you need to type the numbers directly (without tapping caps or shift) as if the shifted position was selected. None of this is stated in the user manual (in English) a bit too succinct.
