My HP-25 begun to act strangely : all the dots on every digit ar lit. I know that's the signal of low battery but my battery are brand new.
All calculation seems to works ok but it's hard to know where is the real decimal dot...
Program is also working good
I opened the calculator and every contacts seems to be ok. Under the display, there is a kind of potentiometer, what is the use of this adjustment (no i don't totch it yet...)
thanks you for all your answers.
