I found this in a comment on Amazon by Craig "hole west of town". By his comments, he was able to pair the iGo with the N800.
TO PAIR your device the instructions are on the back. (press Control, FN (green) and FN(blue) simultaneously. There are no lights on the keyboard so you only know if it is working if it actually pairs.
Once I figured out this small step, which is not in the manual it all went smoothly. effectively the manual could have been replaced with a business card sized piece of paper that had the website on it and words that say "go here for instructions" in all 15 languages. If you are going to need to download drivers anyway, then you may as well get the latest ones.
Do you ever see the green light flashing above the letter T on the keyboard? At least the one I got I have to hold the keys down for about 3 seconds or so then the green light will blink for awhile.
Hold ctrl + green fn + blue fn. A little green light starts flashing.
Go to bluetooth menu>devices>new to look for new devices.
The keyboard will come up, select it and a 4 digit code will be assigned.
Hold down blue fn button and type in 4 digit number code and then hit the enter key.
Voila the keyboard should be connected.
