Dear Sir or Ma'am I have the TI- nspire that has the TI-Plus key pad. I just received the TI-Plus keypad. I install the the keypad and on the screen it shows press Alpha F1-F4 for short cut menu. I see the Alpha key but which keys are F1-F4?

It seems to me that you get the loading bar when you switch keypads. I just switched keypads, and when I reinserted the TI84 Plus keypad back again I found my last TI84 Plus screen contents still displayed.
As to the RAM cleared message, it probably is related to the batteries being depleted.
To verify battery charge level, you may use TI connect.

1. Remove the keypad (for TI-Nspire) or the battery door (for TI-Nspire CAS) and remove at least 1 battery from each column of batteries. After 2-5 seconds, reinsert the batteries and turn the unit on. This will cause the unit to reboot the operating system.
2. Remove the keypad (for TI-Nspire Family or TI-Nspire CAS Touchpad) or the battery door (for TI-Nspire CAS) and remove at least 1 battery from each column of batteries. After 2-5 seconds, reinsert the batteries and LEAVE THE UNIT OFF (do not turn on and then back off). If the TI-Nspire/TI-Nspire CAS is a Clickpad, hold down [Home] [Enter] [P], and while holding these keys, press [On]. If the TI-Nspire/TI-Nspire CAS is a Touchpad, instead hold down [Doc] [Enter] [EE], and while holding these keys, press [On]. The device will boot up as in the previous reset, but will display a menu with the following options. Please try options 1, 2, 3, and 4 in that order. ** The [Home] key is located at the top right of the TI-Nspire keypad and has a picture of a house on it.

i would say use the normal key pad or send it in to T.I to fix.

Remove the TI84 Keyboard, insert the TI-Nspire keyboard and try to reset the calculator with a starightened paper clip.Calculator has a reset button on the back.

Hi
A. Download the TINspire OS from education.ti.com

Use the Ti-Nspire computer link to reload the OS onto the calculator.

4. Run the Ti-Nspire computer link software.
5. The select device dialog should appear, and detect the device.
6. With the mouse cursor, select the OS, drag it and drop it on the main window (file browser window) of the TI-Nspire computer link software.
7. Alternatively, click the menu Tools and select Install OS. A Select file window opens.Use the browse button to point to the OS and click Open/OK

B Installing from another Ti-Nspire ( not a TI-Nspire CAS) if availabe)

1. Connect the two devices using the USB Mini A to Mini B cable
2. The end marked A should be inserted into the sending unit, while the end marked B should be inserted into the receiving unit.
3. Both units must be turned ON
   
4. On the sending unit, access the document chooser by pressing [Home](the house icon).
5. Once in the document chooser, press [Menu] and choose 9:Send OS…

Hope it helps.

Yes, the Ti nspire not only functions as a ti83 but, also operate w/ nice advance math software that any teacher would envey. It comes with the ti83 keypad plus software and great instructions to help the instructor at all levels of math learning. I don't know any better and it is a beautiful plan that ti has set up.
