Perhaps one of the following sources will be helpful:

To reset the TI-89 family, TI-92 family and Voyage 200 graphing calculators, press [2nd] [6] (reads MEM over the key). The [F1] menu appears and contains the following options:

  • All RAM - Clears all variables and programs from RAM only. This will not delete items from Archive or Apps.
  • Defaults - Does not clear any files from the calculator. Instead, this option resets the calculator settings to default, including the Mode, Graph Format, Table Setup, and other settings.
  • Vars - Clears all variables from Archive (Flash ROM). This option will NOT delete Apps or variables stored in RAM memory.
  • Apps - Clears all Apps from Archive. This will not delete any variables.
  • Both - Will clear all Apps and Variables from Archive. This will not delete any Variables from RAM.
  • All Memory - Clears everything from RAM and Archive, leaving only the Calculator OS and its components.
For example, I think you will want to follow the last step above... which would be to press [2nd] [6] [F1] [1] [1] [ENTER] [ENTER].




Also, if you are looking to clear all the RAM in another way I would take a look at the guidebook, which is downloadable from the following site in PDF format.

http://education.ti.com/downloads/guidebooks/graphing/89ti/TI89TitaniumGuidebook_Part2_EN.pdf

Take a look at page 951 and 952 for another way to clear the RAM

If you are truly talking about the the TI89 calculator there is no command to set Diagnostics ON. This is a command for the TI 83/84 Plus. In the TI 89, the correlation coefficient is displayed by default in the statistical result screen.
In the Ti83/84 open the catalog: Press [2nd][0] (CATALOG).
Press D, then scroll from there until the line DiagnosticOn. Select the line and press ENTER.

Ti-89 titanium diagnostics


There is no DiagnosticsOn command in the TI 89 Titanium. The command exists on the TI83/84PLUS where it displays the r and r^2 coefficients. On the TI89 , the correlation coefficient and the determination coefficient (r, r^2) are displayed by default among the statistics if THE REGRESSION MODEL includes them. If they are not defined by the regression model they will not be displayed. In short, you do not have to turn diagnostics ON.

My TI-89 calculators finance app is giving me the wrong answers by a few 1000 or so and increases how far off it is the larger the figure


Make sure your decimals are set to the correct number.
And also you can perform a factory reset on the unit to make sure all is back to normal.
Just be aware that it will delete any information which you have stored into your calc.

Resetting
After using the TI-89 and changing modes several times, you may set the calculator back
to all default modes by pressing 2nd 6 (MEM), F1(Reset) and 3 or by highlighting
3:Default and pressing ENTER. To reset all memory press 2nd, 6 (MEM) then F1(Reset)
and select 1: All.

Hey, im having problems with my TI-89 Titanium, i need it to calculate ((30.000/15.000)^(1/20)-1. Then i get the reuslt 2^(1/20)-1 but i need it to be 0,03. How can i set it to do that?


To display the last result as floating point, press [ ♦] [ENTER]. I hope this one is displayed correctly in the FixYa solution, the first key is the diamond --- green button, below [2nd] and left of [ALPHA].

To make this the default setting, press [MODE] and select APPROXIMATE from the menu.

Ti 89 detected but couldn't get status


Hello,
Here is what the FAQ and Knowledge Base area of the TI site has to say about the problem you are having. Hope it helps.

How do I correct the error message "TI-83 Plus or TI-89 detected, but could not get status" using the TI Connect software for Windows®?

The Operating System (OS) will need to be updated on the TI-83 Plus family or TI-89 calculator in order for the TI Connect software to detect the status. Try the following procedure to install the OS from the TI-83 Plus and TI-89 Boot Screen. Make sure TI Connect 1.6 is installed on the PC.

If using a TI-89 calculator:
• Connect the TI Connectivity cable to the TI-89 calculator and the computer.
• Do not start the TI Connect software.
• Download the TI-89 v2.09 OS onto the PC's desktop.
**Force the TI-89 into the "Boot screen" (see instructions below)**
• "Press I to install..." (press the [9] key).
• Click on Start >> Programs >> TI Tools >> TI Connect >> TI OSDownloader.
• Follow the on-screen directions to install OS version 2.09.
The download should begin.
**Steps for Boot Screen:**
• Take one AAA battery out, press and hold down the [APPS] key while reinserting the battery to force device into the Boot Code screen.
• "Press I to install..." will appear.
Once the OS has completed installation, the TI Connect software will be able to detect the TI-89.

Hello,
There is no such command for the TI89Platinum/TI92/TI92Plus/TI Voyage200PLT. This command exits for the TI83Plus/Ti84Plus and it allows you to get the r2 value for a regression. For the TI89 r squared is calculated by default.
Hope it helps
