The module for my Casio CFX-200 is not fully seated into the case so some of the buttons are not working. I see that the buttons on the sides slip and interfere with the leaf springs on the module, is there a trick to getting them out of the way?
So I took it back apart to take some photos of it then I decided to try again. I used a sewing needle to reach between the module and the case to push each side button in this allowing the module to seat further in. Long story short… it’s working about as well as when I got it in 1987😀. Thanks for your rapid response and I will remember to include photos next time I have a question. JohnFTexas.
