TQ3 potentiometer - What's this for?

[granite]

On the back lower left of the TQ3, there is a white plastic pot adjustment recessed in the case, right next to the screw holding the case together. Does anyone know what it's for?
:unsure:

Thank's rangerfredbob, I probably should have read the manual a little closer!:rolleyes:
