Question about Casio FX-9860G Graphic Calculator

1 Answer

Screen contrast? The writing on my calculator screen started to get lighter, and are now very faint. I changed the batteries, and when I turned it on the screen is still light. I'm not sure whether I should replace the back-up battery or maybe it's the contrast?!

Dark screen


If calculator uses batteries, change the batteries. If it uses solar polar, expose it to direct sunlight or a powerful artificial light (lamp).
Also , in the Mode or Setup menu look for a contrast setting procedure. If nothing works, just buy another calculator and retire this one to the museum of calculators.

Screen too dim


You can try adjusting the screen contrast by pressing [2nd] and using the up and down arrows. Up will make it darker and down will make it lighter/more faded.

My TI-81 screen is so faint. How do I make it


Turn the calculator on. Press and release the 2ND key. Press and hold the up-arrow key to darken the screen/increase the contrast.

Obviously, to go the other way you use the down-arrow key instead of the up-arrow.

The calculator will not turn on a TI 83 plus, batteries changed


You say you changed the batteries. Did you also change the back up battery? It's located in a little door with a screw right above the AAA batteries.

My students have come to me many times and have said that their calculator will not turn on. Most times it is that the contrast on the screen has been turned down and the calculator is turning on but the screen is too dim to see that it's on.

To check your contrast, turn the calculator on, press the 2nd key and the up arrow. This is how you darken the screen. You lighten the screen the same way but you use the down arrow instead.

On TI-83 How do you change the batteries?


Try pressing the 2nd key and then holding down the up arrow key first.  This changes the contrast on the screen- makes it darker.  Pressing the 2nd key and then holding down the down arrow key will make the screen lighter
