My 2 button misses a few presses now and then, particularly if I don't hit it just right or if I am doing multiple quick entries. I know others have had issues with other buttons.
Is this something that gets better with time and usage, or should I be popping the calculator open to do some cleaning?

Re: buttons that don't register well
I'm not sure how fast this could get better on it's own.
If you're comfortable with the following procedure, this will help:
- open the calculator
- open the latch of the LCD connector and release the LCD flex ribbon
- unscrew the two inner screws and remove the electronic board
- lift up the foil partially and clean the contact area and the metal domes of the affected buttons. Use alcohol, acetone or nail polish remover
- assemble the calculator and test it

I've tried acetone, it's no problem at all.

@gruensucher: grrr gleichfalls! Woher soll ich wissen, was du hier meinst, wenn ich nur lesen kann, was du schreibst?gruensucher wrote: ↑Tue Dec 19, 2017 9:49 pmI do not use acetone, preferably as a Teilereiniger (part-cleaner??).



Trying to find out what was really meant by gruensucher. Most probably not what he wrote.
