6. Кыйынчылыктарды
If you encounter issues with your calculator, refer to the following common solutions:
6.1 Дисплей маселелери
- Бош дисплей: Ensure sufficient lighting for solar power. If the issue persists, the battery may be depleted.
- Dim Display: Move to a brighter area. The display contrast might also be adjustable in the calculator's setup menu.
6.2 Calculation Errors
- "ERROR" Message: This typically indicates an invalid mathematical operation or syntax error. Review your input and the function's requirements.
- Туура эмес жыйынтыктар: Check the current operating mode (e.g., ensure you are in Normal mode for basic calculations, or the correct angle unit (DEG/RAD/GRAD) is selected).
6.3 Калькуляторду баштапкы абалга келтирүү
If the calculator behaves erratically, a soft reset may resolve the issue. Press the RESET button (usually a small recessed button on the back, requiring a thin object like a paperclip) or clear all memory via the M-CLR function (often 2-чи Франс анда M-CLR). Note that resetting will erase all stored data and settings.
