Hi, Frederick;
if you wanna give it a try, clear all memory with [ON][-]. Try this:
turn the calculator off;
presws and hold the [-] key;
while pressing the [-] key, turn the calculator back on;
release the [-] key You should see [ Pr Error ] The USER annunciator should be off, now. But youŽd loose all of your data.
