Replying to Forward pressure on sth 12 bindings

Hey guys, I recently purchased a pair of salomon suspects with the STH 12 bindings. The shop was really far away from my house, and I didnt have my boot with me when i went to pick it up so they didn't get to change the forward pressure for me. Apparently it's a really important setting so does anyone have any ideas on how to do this? Any help is appreciated.
P.S- I already did the forum search and nothing came up that really helped me.
