HP 12c reliability - (Pr Error)

I'm having issues with my HP 12c... I keep getting a (Pr Error) and it won't do TVM calculations.

Have any of you guys had reliability issues with the HP 12c? This is a new model HP 12c. The old ones are super reliable (I had lost mine).

i know a 12c shows Pr Error when you hold (-) press ON. This clears the memory. Sounds like another issue though....try changing the batteries maybe?

 

It's funny you mention this because I am having issues with mine as well. Whenever i press the n, i, PV, PMT, or FV buttons, the calculator turns off. When I turn it back on, I'm faced with PR ERROR. Some of the other keys do this intermittently as well. Kind of disappointing, since I had heard such good things about the calculator.

I will try the battery switch.

 

HP12C's have gone down in quality. I get PR errors all the time and I am on my second new calculator in a year. My 20-plus year old HP12C at home still works better than my new ones. I am thinking of trying a whole new calculator.... Maybe Texas Intstruments. HP12cs are no longer reliable.
