How to Switch Keypads for the TI-Nspire
The TI-Nspire (Touchpad or Clickpad) can operate with two different keypads (not at the same time): the TI-Nspire keypad and a TI-84 Plus Keypad. When the TI-Nspire keypad is installed, you are using TI-Nspire. When the TI-84 Plus Keypad is installed, your handheld device works exactly like any TI-84 Plus Silver Edition device. This means that you actually have two handheld devices!
If a TI-84 Plus Keypad was not included with the purchase of your TI-Nspire, you may be able to acquire one at no additional cost. Log on and complete the online form.
To change the current keypad, follow these steps:
On the back of the device, slide the tab to the right to release the keypad.
Slide the keypad down about 1/4 inch and lift it out to reveal the battery compartment.
Place the new keypad gently in place, leaving about a 1/4-inch gap at the top.
Slide the keypad up toward the display screen, applying enough pressure to snap it into place.
Each time that you change keypads and turn on the unit, you must wait for the new operating system to load (as indicated by a progress bar).
Updating the operating system on your TI-Nspire automatically updates the operating system on the TI-84.
