Grazie mille, Massimo ! (Many thanks)
I have done what was written in the manual, now I will try new batteries as per your suggestion but anyway I want a spare unit (even a Chinese one).
I was in the middle of a financial meeting when the calculator died and I borroved a stupid algebric one from a collegue: now I know that I cannot work without RPN !
I am not an engineer but trust me that RPN works better also for marketing and financial people !
Thank you so much also for the link, it is very nice to see how kind and helpful is the people you find in this site !
Best regards,
Ciao
Luca

Many thanks, Renato !
I did as you suggested, also with new batteries, and it didn't work, but after cleaning the contacts and doing it again few days later, it is working again now !!!
I agree with you about the China made units, I bought one as a back-up but the feeling is not the same as my old one !
Thank you again,
Ciao
