The disc was very easy to use. A protective disc sleeve covers the back, instructions are written on the back saying: insert the disc, follow the voice instructions and skip to track III, track III is listed as "You're Done". I inserted my disc but the instructions were unreadable due to a dirty laser lens. I didn't know how long I wanted the disc to play, so I ran the disc to its full length, then emptied the disc and put it in a second time. This time the voice instruction told me to switch to Gauge III after a very short time and everything worked out great.
