change batteries - calculator

hi, When I change the batteries of calculator do i need to change the settings? i forgot what i have to do any idea please? Thank you

What settings did you change after you originally purchased it?

I do not recall? but i think you have to change something… Anyone please?

P/Y=1, (periods per year =1)

what do I have to press? do you just press 2nd function P/Y please? and input 1?

buy a second calculator…with all the money and time invested here…don’t risk it.

i have two already however i do not know if something happens what i need to do to change the settings …
