Question about Casio CFX 9850GB Plus Calculator
You can increase the contrast.
Press [MENU]. Use arrows to select [CONT] icon. Press [EXE] . Press arrow down to [CONTRAST]. Use + or - to adjust. You can also adjust color individually, or press [F1] to set the factory default.
If all this does not improve the display, you may have to install fresh batteries (main batteries).
Hope it helps.
