⚠️ Before You Reset: Crucial Tips & FAQs
Before resetting, make sure you back up your calculator programs using TI Connect CE and a USB cable:
- Install TI Connect CE from the Texas Instruments website.
- Connect your calculator with a USB cable.
- Open the software and use the Program Editor to send your programs to your computer for safekeeping.
If the screen is unresponsive, perform a hard reset:
- Locate the small reset button on the back (near the battery).
- Use a paperclip to gently press and release it.
- The calculator will restart — this won’t delete programs or data.
No. Resetting memory (RAM or All Memory) does not remove the OS. It stays intact unless you deliberately delete it with special tools — which is not recommended.
For your privacy and security, perform a Full Factory Reset to wipe all your personal data before giving it to the next user.
