Info: The two pictures are showing a modding, in other words… budding the Square Root function to convert it in a possible CASIO: R3 SPIESS Heinz: After I looked at the square root hack from the inside, I started to remember the story: By coincidence I had found out that hitting the [%] and [-=] at exactly the same time, the square root of the current value was displayed. But since it's rather difficult to hit those two buttons exactly at the same time, I installed that switch, which 'short cuts' the reed switches of the two buttons. So to compute a square root, one has to put the switch to 'Wurzel' (can be done while power is on) and then hit either [%] or [-=] and then one can put the switch back to "Normal" to have the standard functionality of the 2 buttons.
