0.0000 is the calculator's clear screen. To turn it off, press the green arrow then the ON button.

I received this camera a few years ago as a gift. I used the batteries that came with the camera but when they died I put in new alkaline batteries and ever since the camera has been stuck with a message...


you might have cooked it..... fresh alkaline batteries carry a voltage of about 1.7v.
try turning it on/off multiple times to see if it will clear the fault.

Cant get Y values when i type in X values in table


Hi there,

Well first of all you can try to reset your calculator, just follow the below steps to know how to reset it -

1. Turn off your TI-83 Plus.
2. Open the battery panel on the back of the calculator and remove one of the AAA batteries. Keep this battery handy, as you'll need it again.
3. Press the "Clear" button, and keep it held down.
4. Put the battery back in and turn on the calculator, with the "Clear" button still held down. When the calculator's screen displays the message "RAM Cleared," release the "Clear" button.
5. Remove one of the calculator's batteries again. This time, hold down the "Del" key.
6. Reinsert the battery and turn on the calculator. Release the "Del" key when the screen reads "Waiting...Please install calculator software now."
7. Use the TI Connectivity cable to connect your calculator to your computer. Run the TI Connect software to reinstall the calculator's operating system. If you don't have an up-to-date copy of TI Connect, see Resources.
8. Turn off the calculator and disconnect the TI Connectivity cable. Remove the AAA batteries, as well as the small, circular lithium battery.
9. Wait five minutes before putting the batteries back in. Turn on your calculator.
Hope it helps ..........

Good Luck!!

Thanks

Wrong language on garmin oregon 400t


I called Garmin for this very same reason. The answer is; while your GPS is off place your index finger in the upper left of the screen, turn on the GPS, a screen will come up and ask if you want to clear the GPS (or something to that effect), say yes. (Yes is the top button) Then you can choose english. YAY!

Ti 83 black screen problem


i had the same problem. If you hit 2nd down 2nd down 2nd down and keep repeating untill the screen clears it should solve the problem. i tried the other solutions that tried clearing the memory and they didnt do anything but erase the equations i had previously put in it (great). But this should work.
