The noise level on the MF101 LPF is a big letdown

Hello,

Can you please help me in getting UNITY GAIN on my MF-101 please? Where should the KNOBS on the Unit and my Guitar Volume be initially to get the YELLOW LEVEL LIGHT to come on on the MF-101 please? All cords are new as is the Unit. I did it when I first got it, but now, I forgot the specific steps.

Thank you in advance.
