Like Texas Instruments' other graphing calculators, the TI-83 features the ability to store variables and equations as lists. The calculators feature six list templates, L1, L2, L3, L4, L5 and L6. On the TI-83, you can rename the "L" lists, edit them or add up to 14 more lists to accompany them. If you have no need for the "L1" list, you can delete it all together.
Turn the TI-83 "On." Press the "Power" button -- the blinking cursor should appear on the screen.
Press the TI-83's "Stat" button. Press the calculator's "Enter" button to select the "Edit" option from the "Stat" menu.
Move the cursor over "L1," using the calculator's directional keypad. Press the "Delete" button to remove "L1."
Press the TI-83's "2nd" button to access the secondary functions of the TI-83's buttons. Press the "Mode/Quit" button to access the calculator's "Quit" function and return to the TI-83 home screen.
Tips & Warnings
- To restore L1, or any of the other "L" lists, open the TI-83's "SetUpEditor." Return to the "Stat" menu, and then select the "SetUpEditor" option from the "Stat" menu. Press "Enter" in the "SetUpEditor" to revert back to blank L1 through L6 fields.
