Buttons dont work

If the calculator has the latest OS version, additional menu items are available by pressing the ALPHA key, followed by a function key F1, F2, F3 or F4. One of these choices allows user to select improper fraction display or mixed number display of results.

The function keys originally have twp functions: One function accessed by pressing a function key directly, the other by first pressing the 2nd key then the function key.
With the newer operating systems, there is a third function associated with the function keys F1.F2,F3 and F4, but not F5 nor F6. This third function is revealed after you press the ALPHA key.

When the ALPHA key is pushed the cursor shows an A. Press one of the keys that has the same color as the ALPHA key (A,B,C,...X,Y,Z).
If you have the MathPrint OS, the ALPHA F1/F2/F3/F4 sequence activates shortcuts to newe features (fractions, logab, sums etc..)

I just had this problem: shortcut menus used to work, but stopped, with TI Version 2.55 MP. I discovered that running the preloaded app PlySmlt2 (others work, too) and quitting it fixed the problem, but that later running a non-TI app caused the problem again. So the non-TI app may be misbehaving, as suggested in this TI knowledge base article.

Use the >Frac and >Dec commands in the MATH menu. Press the MATH button to bring up the menu.

Press APPS. Scroll up or down to reach Inequalz and press ENTER. The inequalz application will know control function graphing. Open the Y= editor to enter at least two inequalities . Use the tabs at the bottom to type in the relational operators. You will have to press [ALPHA] followed by [F1], or [F2], etc


Press the GRAPH function key (F5) to draw the graphs. You get the two regions superposed (original shading).


Press [ALPHA][F1 or F2] to activate the [SHADES] tab. This open up the following screen.


On this screen you can choose the type of shading 1: Intersection of the two regions ( the part of the plane that satisfies both inequalities, 2 the union of the two regions or 3 the original shading (as compared to choice 2). Selecting option 1:intersection gives you the following screen.


If you press the [ALPHA][F5] keys you have the HELP ? screen below.


If you press the [ALPHA] [F3] keys you get a Point of Interest (You should consult the manual for the Inequalz application for more details.

By pressing the TRACE button (not ALPHA F4) and the left or right arrows you you can follow the graph of one of the functions. You jump to the other functions by pressing the Up or Down arrows.


To get the manual for Inequalz go to the education.ti.com and download it.

Hi...

You can access F1 by

1. Press and Release "ALPHA" Key
2. Now press desire function key. Here in this case, Press "Y="

Many keys in this calculator serves one than one function which can be access through by pressing either "2nd"(Blue Key) or "ALPHA"(GREEN KEY). Such extra functions are noted on keys in Green or Blue color. These additional functions are accessed by first pressing corresponding color key and desired function Key.

For example:
pressing UP and DOWN keys navigates the screen up and down
if we press ALPHA key and then UP/DOWN key, it will scroll screen UP/DOWN by a page. Also you can use this combination for copy functions.
if we press 2nd Key instead of ALPHA, we can change Contrast of The screen

the F1-F4 keys are located at the very top of your keypad. They are also known as the 'Y=' WINDOW, ZOOM, TRACE, and GRAPH keys. If you look at these keys you will see f1-f4 printed on them in green.

The calculator OS has been upgraded to the version 2.53 MP.
For this version, whenever you remove batteries (or replace them) and turn calculator ON, you are reminded to Press [ALPHA][F1-F4] to locate Shortcuts Menu.
The calculator also asks the user to press either
[1:Do NOT show Again]
[2:Continue].

Here is what these cryptic messages mean.

Certain functions implemented on the new OS are available by pressing the [ALPHA] key followed by F1, F2, F3 or F4.
Since you may forget how to get to them, the calculator gently reminds you that there are other functions accessed only by pressing the [ALPHA] key.
It also gives you the option to flash the reminder every time the calculator memory is reset (CONTINUE) or NOT to SHOW the REMINDER again.

Usually after the RAM cleared message, press [2:Continue] or any other key but [1: ] to keep being reminded how to access the new functions.
Once a key is pressed the screen is cleared and you have the solid blinking cursor.

i finally fixed my calculator~

1. if you have a ti 84 plus silver, plus, or just ti 84, find a friend who has either a ti 84 plus silver, plus, or just ti 84. (as long as the number is the same)

2. link the two calculators together

3. using your friends calculator, press the [2nd] and the one next to alpha [x,t,o,n]

4. go all the way down to [send os]

5. send it to the other calculator and your problem should be fixed
