Need to Adjust Temperature Setting on My harbor Freight/Cen-tech "Pinpointer'

Well I'm still using my genuine, imported, (from far, far off in the Orient) modified, harbor Freight, Cen-Tech hand held Metal Detector/"pinpointer".

It's still working great but I still have the problem of it getting too hot and not working. There's an adjustment on the board to set it to the ambient temperature. I know that some people drill a hole over the adjustment screw and carry along a small screwdriver to make on the fly adjustments if necessary.

This is what I want to do but I need to know where exactly on the board the actual adjustment screw is. I already know that the blue pot is the overall sensitivity adjustment. I just need to know where the one I need is so I can drill my hole in the right spot.

I'm trying to do this without opening it up again if that's even possible. The wires in this thing are SO delicate I don't want to risk breathing on them or anything if I can help it. One false move and these things can be toast in a second.

Such a fine machine.....

Any help/suggestions will be greatly appreciated.

Thanks in advance.
