If you started with the E 6 you might be a bit lost in learning your machine. My suggestion is to download the DM 80 manual and use it to compare to your E 6 manual. I like to have them both online so I can refer to them without going to get my hard copy of the E 6 manual. It really helped me when learning the machine since I started with the E 6.
