Unfortunatley the cooker does appear to have as defrost mode. It has two twisting knobs (on the left for selecting things like lamp, auto, dual, set band memo) and on the right is just a knob with +/- to higher or lower tempreture). In the midlle is two buttons which are "<<" and "OK"
Have tried everything and most of the stuff listed above is not applicable to me (clock function buttons) or temperature function buttons. I have even tried the phone number you gave me and cant get through. I am based in Ireland
