12C Problem

[John B.]

I purchased my 12C over 16 years ago. I turned it on a week ago and there was no display. I was not warned of a low battery charge before this event. I decided to replace the batteries and the calculator did not turn on immediately after; rather, it began to work a few hours later. Even though it worked, an asterik was flashing in the lower, left corner of the display. Today, nothing happens except when I lay it flat; and the only thing that appears (very faintly) in the display is 219,00 with the flashing asterik.

Any immediate help or comments are greatly appreciated. I would hate to replace this 12c if all that is required is a quick fix.
Thank you!

Hello,

Seems to be a power problem.

a) clean up the contacts, with a rubber for example.
b) clean up the contats of your batteries. They should be immaculated.
c) should the problem persist, test your batteries, there is a chance that they ar not as good as you think they are (LR44)

Good luck !
