|
Cleaning a TI graphing calculator: |
| • | Use a cloth, lightly dampened with water, to clean the graphing calculator's screen. Never use solvents or other cleaning liquids.
|
| • | Avoid applying pressure to the screen/display.
|
| • | Keep foreign objects from penetrating the connectivity ports on the unit. |
| • | Keep liquids from getting inside the unit. |
|
Storing a TI graphing calculator: |
| • | Place the slide case over the front of each unit.
|
| • | If the unit is being stored for more than 6 months, remove all four (4) of the AAA batteries.
|
| • | Store the unit in temperatures from 50 to 86 degrees Fahrenheit and with the relative humidity not exceeding 85 percent.
|
| • | If one battery in a set has a leak, discard the entire set of batteries. |
|
Troubleshooting a TI graphing calculator: |
| Calculator won’t turn on? It may be something as simple as adjusting the contrast of the screen. Find other troubleshooting tips.
|
| • | Make sure you have updated your calculator with the most recent operating system (OS) for the best performance.
|
| • | If you are receiving error messages or unexpected results, visit the TI Knowledge Base for answers to basic questions and common issues. |
|
Battery Information Conservation |
| • | Store handhelds in a dry, temperature-controlled area because extreme temperature ranges can reduce battery performance.
|
| • | Use non-rechargeable Alkaline batteries for improved performance and safety.
|
| • | Avoid mixing new batteries with old batteries, and different types and makes of batteries.
|
| • | Do not remove both the graphing calculator’s “AAA” and lithium batteries at the same time. The round lithium (or button) battery provides auxiliary power while “AAA” batteries are being replaced. This will protect data stored in the unit’s memory.
|
| • | Update your handhelds with the most recent Operating System (OS) to provide the best battery life possible. |

Note: TI-Nspire with Touchpad and TI-Nspire CAS with Touchpad handhelds also have a rechargeable battery sold separately.
