My calculator automatically adds a 9 to my last number every time I try to do math. For example, I type 5 + 6 and expect =11, but calculator does 5 + 69 and I get =74 :( The 9 button does not appear to be sticky.
Technical support just helped me fix the same issue. You need to reset the calculator. Press the “2nd” key followed by “0”. Arrow down to option 2 “yes”. Problem fixed.
One of my calculators is adding a digit to the end of each entry. I know how to reset the calculator but when I try, I am unable to arrow over to Y on this screen: RESET: N Y I also tried holding down ON and CLEAR at the same time but that is not working to reset the calculator either.
shorted PCB keys, try to clean the PCB keys with alcohol (To dismantle, you’ll need to apply hot air on the boss around 200°C)
Does anyone know how to do this on purpose?
