hp 11c "error 4"
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 Thomad |
