While I was so happy to test this feature, I had the idea to turn it off, and to execute a self-test (ON/(holding the key /)). Now, when I try to turn on my calculator, nothing works. Does someone know how to fix this problem?

You will have to do a hard reset of the calculator.
I don't remember exactly the method, but I think there is a reset hole inside the battery compartment.
It has been mentioned in other posts in this section about the 15C ce.

The 16C mode and the large memory mode do not support the self test, so not a good thing to try to do

Good luck, it is recoverable.

Thanks for your answer. It took a bit of time until today (I did not have the tools to open the battery compartment and to execute a hard reset), I have just tried today the solution of the reset hole, but unfortunately, it has not worked

When I hold the reset button a few seconds (maybe 5 seconds), "Pr Error" is displayed when I turn on the calculator. But, when I press another key, there is nothing anymore on the display.

Is there anything else to do in addition to the reset hole? How could I fix such a problem?
