My first move would be to go to the store where you originally bought the bow and ask them if they have a copy of the owner's manual that you can have copied for your files. Usually stores keep copies of these things especially if they service or repair the bows. If this fails, you could try making a phone call to the Barnett company. If they ignore email, they most likely will also ignore snail mail. If those ideas fail, the next thing you will need to try is to find another Barnett owner and see if they have a manual. They may not because most people either throw them away or loose them. I don't now why, because as you can see, they are valuable when you need them. I always file all of my owner's manuals in a filing cabinet where I can find them when they are needed. Every couple of yhears I have to go through it and remove manuals for stuff that I have thrown away. If I sell anything in a garage sale, I always include the owner's manual which I have kept on file.
