HP 15C

I have a fairly new HP 15C Limited Addition calculator.  When I turn the device on, "Pr Error" appears on the screen.  When I press any buttion to clear this error, the caculator turns off.  I have removed and replaced the same batteries (in an attempt to "reset" the calculator).  This doesn't seem to help.  Any advice, please?

Hi,

 

Have you tried to hold down the - (minus) key and turn it On ?

 

Regards.

Hi,

 

I think you should try new batteries. A reputable brand from a reputable source. Make sure the "+" of both cells are visible when replacing.

To Whom It May Concern,

 

When I tried the minus (-) and the on button, it did not work.  So I replaced the batteries and the Pr Error message went away.

 

Thank you for this post.

 

Sincerely,
