CASIO FX-83ES - reset to factory settings

Please could you tell me how to reset this calculator? Back to factory settings?

I have a calculator CASIO fx-9750GA. I want to convert certain decimals into fractions and when I press the d/c button it says "SYN error" I don't know what that is? I tried pressing Shift and then the Set-up button and the first option is Mode and the one below it is Func Type. Across from Mode it says "comp" I don't know how to change from there either. Please help. I rather use the d/c button, why is it not working?

SOURCE: converting decimals to degrees on a casio fx-83es calcualtor

if you mean degrees like the degree/minute/second thing: lets say you have 24.12 there is a button that has a dot, and 3 commas (it's located next to the negative button) that will convert that number to degrees. input your decimal, press the equal sign, and then press that degree button and it will convert 24.12 to degrees, minutes, and seconds. the solution is 24 degrees, 7 minutes, and 12 seconds.

Hi there, i have the same problem with the Casio fx 83ES. Simple Sums difficult without Exp?


The Enter Exponent key may be marked as x10^x. It is in the last row of keys, near the =/EXE. To enter a negative exponent use the change sign key (-), not the minus key for subtractions.
