2. Press and hold # and 6 keys.
3. While holding those keys plug the power cord back in.
4. Wait until the screen goes blank before you release those keys.
5. Follow on printer screen instructions.
Hi, The batteries may be depleted, and they need to be replaced. If abtteries are fresh and the calculator seems toi refuse to turn ON, the screen darkness must be increased before declaring that the calculator does not start. If screen is too light you won`t be able to see that calculator is already ON.
To increase the contrast.
Press the [2nd] and release it.
Press and HOLD the UpArrow key until you can see something on the screen.
The screen may have about 10 levels of darkness
