I bought a calculator last month. But I don't know what's going on, it's always good or bad. Sometimes he can't display what I typed. what should I do?

test by pressing all the number from 0 to 1
if some are working it’s likely to be water damage
if not you gonna need to reset it using the MODE 9 combination
