HP-28S Beeper Message #1 Posted by MJ Meiners on 10 Oct 2002, 9:32 a.m.
Does anyone know how to turn the "Beep" off on the HP28-S? I have long ago lost my instruction manual. I have my PE exam in a couple of weeks and they will not allow my calculator beeping every time I enter something incorrectly. Thanks in Advance
