AHH! please help with Line 6 FBV Express foot controller

Ok, I just purchased a Line 6 FBV Express foot controller and no manual came in the box. I figured out the ethernet connection and channel switching thing quickly enough, but I have two problems I was hoping someone would help me answer?

1) I can't switch from volume to wah. I have been stuck on volume since I got the thing.

2) I can't hook up my other effects pedals without getting this nasty squeaking sound. Is there some sort of manual calibration require?

Any help would be extremely appreciated. Thanks

toe down really hard (until it goes click) to switch to wah
