To clear your calculator back to default, to the following:

CLR (the button 9)

Try a reset SHIFT 9 (CLR) and reset 3:All

Also if Mode:1: COMP gives Complex, maybe MODE:2:CMPLX will give you the usual COMP mode. (wires may be crossed). I have a calculator that has two keys inverted. I made a note of it and keep it taped inside the sliding cover.
