Troubleshooting
| Problem | Solution |
|---|---|
| Calculator does not turn on. | Ensure the battery is charged. Connect to a power source using the USB-C cable. If the issue persists, try resetting the calculator by pressing the RESET button (usually a small hole on the back, requiring a paperclip). |
| Screen is blank or frozen. | Press and hold the ON button for a few seconds to force a restart. If unresponsive, perform a hard reset using the RESET button. |
| Incorrect calculation results. | Check your input and ensure the calculator is in the correct mode (e.g., radian/degree, float/exact). Refer to the operating instructions for specific function usage. |
| Battery drains quickly. | Reduce screen brightness. Ensure the calculator is powered off when not in use. Avoid extreme temperatures. If the problem continues, the battery may need service. |
