I have the hp12c financial calculator. I have been using this for the past 4 years now. For the past few days the screen displays the alphabet "c" on the bottom right hand side of the calculator..i don't seem to have any problem with the calculations so far, but I have my CFA exams coming up in few days and want to make sure if everything was ok.
I went through the archives and found that someone else also had the same problem but I am not able to follow the same steps mentioned in the archive(I don't have the CF on the slant side of the digit 5). Can someone help me solve the problem?

To remove it, press STO then EEX.

Please, Gene, explain:

what does mean STO EEX? What function does it bring?

From page 64 of the HP12c platinum owners manual.

"At your option, the calculations of i, PV, PMT, and FV can be performed with either
simple interest or compound interest accruing during the odd period. If the C status
indicator in the display is not lit, simple interest is used. To specify compound
interest, turn the C indicator on by pressing STO EEX. Pressing STO EEX again
turns the C indicator off, and calculations will then be performed using simple
interest for the odd period."

Funny, but I can't find the link to the manual on the 25th anniversary 12c web page.

Well, thanks you.
