Vortex Sound Research

I'm getting my modular gear out after 2-3 years. I'm trying to play my Shruthi-1 but my tuning is all messed up (only some of the notes work). I emailed with Emilie and she told me to go to the tuning page and set the parameter to "equ." I can't for the life of remember how to get to the tuning page. I've been going through the manual but it is very involved. I want to get some synth lines going. Can anyone help me out?
