I didn't know about that special key menu when pressing {8}.
Btw, when you put your finger on the solar panel, you will see the message "Battery MODEL OK!" after pressing all the listed keys. And when removing your finger from the panel, the message "Solar MODEL OK!" will appear.
Also note that you have to press the {x} key (above {ln}) on an fx-991EX or fx-570EX when it asks for the {logab} key. This is because other models have two dedicated log keys.
