If you press the setup key then 1 under FSE it will say TAB (0-9)? enter the amount of decimal places you want and it will change that for you.

Hi cherycooney,
Press the '2nd' button, press the 'M+' button. 'NP' should appear on the display screen, and print function will be turned off.


Thanks for using Fixya.

Installing new battery


Turn the calculator over. Look for some small screws that fasten a 1 or cover to the body of the calculator. Loosen the screws and remove cover. You should find button cell batteries. Before removing them make a note of the sign you see on the batteries (+ or -) while they still in place. Replace the batteries with the same model or equivalent ones. Replace the cover.
For more detailed instructions consult your calculator's manual.

TI-83 Plus Calculator, battery corrosion, wont stay on and when it stays on for awhile, it turns back off. ON the Calculator it show that the Ram is cleared. want to know what that means and how long...


When it says that RAM Cleared every time you turn it ON, that means the backup battery is depleted and needs to be replaced with a fresh one. The calculator has an automatic power down to save energy.

Wont turn on


Good morning, afternoon, evening or night; whatever time of day you are viewing this solution post. Thank you for choosing FixYa to assist you. You are having problems because you calculator won't turn on. I think you should try changing the batteries. Did you know that your calculator has two batteries powering it? Not only are the 4 AAA batteries powering it, but there is also a CR 3V Lithium Back Up battery powering it as well. First, try changing the 4 AAA batteries. If that still does not power your calculator properly, you will need to replace the lithium back up battery. You can find this at a department store or store that carries electronics. To do this, open your regular battery compartment. Above the AAA batteries is a compartment that says "BACK UP BATTERY CR1616 OR CR1620" with a picture of it. Use a small crosshead screwdriver to open the compartment. Take the old battery out and replace it with the new one. Rescrew the lithium battery compartment back on and close the AAA battery compartment. Turn on your calculator and see if that works. I hope this solution solves this.

I put in fresh batteries but the calculator won't turn on.


Hello,

If new batteries did not solve the problem, the next thing to check would be the battery terminal.

If the battery terminal is rusty, the battery power won't contact and the calculator won't turn on. So, use a flat small screw drive to scratch the battery terminal so that there would be contact.

If the above is not the problem, the next to check would be the wire connecting the battery terminal to the the calculator's main board. There is a wire between the battery terminal and the calculator board. When the battery is inserted, the power from the battery goes from the terminal to the board through this wire. There is a possibility that this wire is cut in-between or is loosing contact. In this case, you need to get a small screw driver and carefully disassemble the calculator in order to check the wire.

If the wire is intact, use a light brush to brush the calculator board as there might be dust on the board.

If non of the above helps, then it means the calculator is dead and needs a replacement.

Regards.

Was using the calculator today, then it shut down...will not power-up...the AAA batteries work on other devices


TI calculators have an annoying habit of dimming the screen when the batteries are changed so that it appears as if the calculator isn't turning on. Turn the calculator on (or at least press the ON key). Press and release the 2ND key. Press and hold the Up-arrow key for a few seconds and see whether the screen becomes legible.

If that doesn't work, try resetting the calculator. Remove all four AAA batteries. Press and hold the ON key for ten seconds. Replace the batteries and turn the calculator back on (you may have to adjust the screen contrast as described above).

TI-83 Plus ram cleared message when turned on


It calculator tells you Ram Cleared each time you turn it on, the most likely reason is that the backup battery is depleted. Its role is to keep the memory modules electrically refreshed when calculator is turned off. If the backup battery is dead, the memory is erased when you turn calculator OFF. Main batteries no longer supply power and the contents of the memory are cleared.
  1. Check that main batteries are good and inserted in calculator.
  2. Turn calculator OFF.
  3. Replace the backup battery.
  4. Turn calculator ON.
  5. Press the [CLEAR] key to erase the "Ram Cleared" message.

Calculator won't turn off with new battery installed.


Hello,
If they are solar powered and if the power down button is not functionning I would not worry about them. Usually battery powered calculators have an automatic power down feature, and sometimes solar powered machines as well. The only free thing we get is the sun's energy. Maybe not the only one (oxygen).
Hope it helps.

Calculator will not come on at all


Hello,
Replacing the battery will always do good. You will be assured that the problem you may be having is not due to spent batteries, so that you may focus on other potential causes.
Hope it helps.
