I left the calc apart in rest for a while (whole a month). It didn't turn on, so that I put the four batteries in charge, after that the message "trying to recover the memory" or something like that...appeared (yes or not in the choice)>>>YES ofcourse, then, lost my preferences (like for example the RPN setting)...?!!! Every time I turn on the calculator always the same message and request...I think it should be the backup battery...I'll go to replace the coin cell...(??!!!) the calculator has no more than two years I think and the manual recommends to replace it every 5 years..........What do you think?

EDIT: I changed the coin cell without success, then inserted four new cells AAA and the alarm is gone. The best advice I can give to myself now, is to run and recover my voltmeter which take rest in the attic, after the move, under 2 cm of dust!
