Question about Canon F-603 Calculator
I'm a math teacher that has three Canon F-603 Scientific and Statistical Calculators. All three have been somehow changed into Hex Mode by unwitting students who have no idea what they did to get them into that mode. I have tried to fiddle with things for the past two years to no avail. These are older calculators that I inherited with the room that I now teach in, so there is no manual to refer to. What are the key strokes to get out Hex Mode?! (And yes, I've tried hitting the Mode key numerous times!)
