I have a 12c hp calculator. Some time ago, the display showed "c" in right side corner and I cannot get rid of this. Please let me know how to erase this. Thank you.

turn off your calculator. Hold down the decimal button . while you press the ON button.
This will reset it back to decimal points for fractions and commas to separate 1,000´s

I have the comma (0,00) issue. Were you able to correct the issue?

Hi,
I am looking for a "Owner´s Handbook and Problem-Solving Guide" in French for my HP-12C.

Hello,
I would like to request specific instructions on how to solve for the IRR of a life insurance product, using my HP12. I have the date of purchase, four premium payments and a death benefit. Any help would be appreciated! Thanks in advance.

Seems like a common refrain, no handbook, but. In my display I have an asterisk in the lower left hand coner and I do not know why it sits there pulsing. I thought it might be weak batteries, so I replaced them and it does not seem to have any impact.

Does HP 12C calculate on 360 day or 365 day interest calculation when calculating payments for amortized loan.

My HP12C runs well, but has a "blinking asterix" on the lower left hand corner of the display screen. IS that "normal"?? What is that telling me?? Can I delete it??

I have just downloaded a the basic 12c calculator program to my handheld iPaq PDA and wanted to calculate accrued interest for bonds. From your tutorial it talks about pressing X> but I gather that must be a key on the 12c Platinum, since I can´t find a X> key on the 12c. Can anyone advise?

Your strange 12C display may disappear if you short across the battery terminals from end to for a moment with the batteries in place. Several shorts may be needed. Use tweezers or metal paper clip.
