Falcon MD20

I lost the manual. Can anyone tell me how to adjust the sensitivity versus the ground balance?

Sliding the ring while twisting it ( up or down ) adjust's the sensitivity.
Unless you have changed it's position from where it was to start with
it should all ready be set. I don't have mine any more but if I remember
you set the GB like you set any detector,
