Hello,
my headset is not recognised by my laptop!!!
if you had paired it to other device before then you have to reset the bh503 first by pressing the M/F (on/off) button and high volume button at the same time until the red light blinking twice indicates the bh503 is resetted. press the on button again until blue light comes out.Then try to add the bh503 using the devices and printers windows.I assume that you have already installed the bluetooth driver or if you are using windows 7 it will automatically updates the driver if you already turned on the bluetooth adapter on your lap top .
