Hello,
When i perform the calculator's selftest (on/X) It displays "ERROR 9" . Then i press a key, and than, everytime, it display's "3" . I know that ERROR 9 means that the calculator needs srevice. But what does the "3" means? I can't find anything wrong with the calculator. It performs all calculations, and holds memory and programms. Does an "Error 9" statement not necceseraly means that ther is something seriously wrong with the machine. Can i still trust the outcome of all calculations?
Thanks,
Erwin
