Hello all,
I was wondering if anyone else had this issue and if they were able to fix it. Basically, every time I press the 1/x key, my calculator automatically shuts off and then when I turn it back on, it displays “Pr Error.”
I know that this is the message the calculator gives in the event of a reset to factory defaults, but I’m obviously not trying to reset it but trying to reciprocate!
Any help is much appreciated. Thank you

Not had that problem before. Thanks for the heads up!

No idea – but I found a page that discusses a problem that’s possibly similar to yours… http://www.hpmuseum.org/cgi-sys/cgiwrap/hpmuseum/archv016.cgi?read=105659

Luckily the problem appears to have solved itself. The problem in that thread isn’t exactly what I had but thanks for the help anyways.
For anyone else who might run into this, I think the problem may be the result of dying batteries (as discussed here http://www.wallstreetoasis.com/forum/s/hp-12c-reliability-pr-error)
