Keypad changing and battery replacement

Your TI-Nspire™ handheld operates in two modes:

• TI-Nspire
  
  
• TI-84 Plus Silver Edition

Dual Keypads

Your TI-Nspire handheld works with two keypads: the first is the TI-Nspire keypad and the second is the TI-84 Plus keypad.

Changing the keypad

Caution: When changing keypads, be certain that the handheld is completely powered down before removing the keypad. Removing the keypad before the display clears may result in loss of data.

1. Remove the cover, and turn the handheld over. Slide the latch release to the right.

   The keypad releases.

   
   
   
   
2. Turn the handheld right side up, and slide the keypad away from the display screen.
   
   
   
   
   
   
   
3. Lift the keypad off the handheld.
   
   
   
   
   
   
   
   
4. Insert the other keypad.

   Ensure that it fits comfortably into the guides on the bottom and sides of the handheld.

   Note: The keypad does not slide in from the bottom edge of the unit. Instead, fit it into the guides just above the batteries.

5. When the keypad is properly seated on the handheld, push the keypad toward the display screen.

   The keypad clicks into place when properly seated and completely inserted into the handheld.

   
   
   

The TI-Nspire math and science learning handheld uses four AAA batteries that are provided with the product.

Replacing batteries

Caution: When removing the keypad to change batteries, be certain that the handheld is completely powered down. Removing the keypad before the display is cleared may result in loss of data.

1. Remove the keypad from the handheld.
   
   
2. Carefully remove the batteries.

   Caution: You may need to use a tool to remove the batteries as they fit tightly in the unit. If you use a tool, be careful not to damage either the batteries or the handheld.

   
   
   
3. Insert fresh batteries.
   Ensure that the + side of each battery faces away from the display screen.
   
   
   
   
   
4. Replace the keypad.
