Marlow I wanted to welcome you to the board but sorry that you have back problems. I don't know anything about the DRX9000 but wanted to suggest that you find the "search" box right under Health Message BoarRAB on the left side of the screen. Enter DRX9000 and it will bring up the previous posts on this subject. There are several entries. I am sure if there is anyone on the board at this time that has knowledge of this procedure they will respond.
