hp 11c "error 4" - hajrigf - 08-11-2015 06:45 PM

On my hp 11c calculator, whenever I try to use any of the 5 left hand upper corner white-text functions (SQR, ex, 10x, yx, 1/x), the calculator returns an "Error 4" message. What could the problem be?

You have probably switched on the USER-mode. Thus these keys try to execute programs A-E which apparently don't exist. You can switch it off with: f USER

Kind regards

You were absolutely right. I switched it off using f USER and it worked. Thanks a lot.
