You can get a manual for the Dynapath control from Dynapath. They are a bit pricey at around $200.00, but its really worth having. Its about 3/4" thick, and it will answer all of your questions......it is well written.
I work at a shop periodically that has a Lagunmatic 320 with a Dynapath 20 control. As I sit here at home, I can't tell you the exact procedure......but if I was standing in front of the machine I could guide you through it easily.
You won't be disappointed with purchasing the manual.
I'm sorry my memory isn't good enough to walk you through it from home......I only run the machine once a month or so when I'm needed by the owner.
