CNI driver pot assignments? zero bias cureent?

[csmn]

I have a problem with an CNI 473nm laser. The laser seems to have to hi zero bias current. The laser emits some light even when modulation input is 0v. Does anybody know the pot to adjust?

Some time ago I did some work on the same driver. I made some notes that indicates the POT
next to the white connector with the red/black wire is the 0 Bias adjustment pot.
I can't guarantee if these notes are 100% correct...
