Thats a key step in pairing- type the code on the board. It doesnt appear to be doing anything, but that registers the board..type the 4 digits you see and push enter. Oh, it goes with out saying you need to be sure the green light on your board is flashing while you do all this.
Today I had the good fortune of going in the conference room, turning on my N800, taking out my IGO stowaway; opening it and by some miracle I have yet to understand- Bluetooth indicator went blue and I was writing in the note text editor with no additional pairing or hassling.. Worked all day and never lost contact too. What a pleasure.!
