Dry your beads until they are completely white........put them in the humidor and leave it alone for a couple of days, don't open it.
After a couple of days, check your beads to see if they are pulling humidity in and turning clear to one degree or another.
As mentioned above, keeping your humi somewhere around 75% full will help both to absorb RH and regulate normal fluctuations as you open / close it.
Above all, patience is the key. You don't want changes in your humidity to be drastic or fast.
