Trigonomeetrilised funktsioonid
Kasutage patt, cos, tan for sine, cosine, and tangent. Inverse functions (patt-1, cos-1, tan-1) are accessed via 2. F.
Logarithmic and Exponential Functions
Keys include logi (tavaline logaritm), ln (natural logarithm), 10x, ja ex.
Astme- ja juurfunktsioonid
Kasutada x2, x3, √ (square root), and 3√ (kuubikujuur).
Mälu funktsioonid
The calculator has 8 temporary memory buttons. Use STO (Store) to save a value and RCL (Recall) to retrieve it.
Statistilised arvutused
Statistikarežiimi sisenemiseks vajutage REŽIIM seejärel valige STAT. The calculator supports 1 and 2 variable statistics. Refer to the on-screen prompts for data entry and calculation of statistical values like mean, standard deviation, etc.
3. Režiimi valik
Vajutage nuppu REŽIIM key to switch between Normal and Statistical modes. Ensure you are in the correct mode for your calculations.
Hooldus
1. Puhastamine
To clean the calculator, gently wipe the surface with a soft, dry cloth. For stubborn dirt, a slightly damp cloth can be used, but ensure no liquid enters the calculator. Do not use abrasive cleaners or solvents.

Veaotsing
| Probleem | Võimalik põhjus | Lahendus |
|---|---|---|
| Ekraan on tühi või tuhm. | Päikeseenergia jaoks ebapiisav valgus või aku tühjeneb. | Move to a brighter area. Replace the LR44 battery. |
| Kalkulaator ei reageeri klahvivajutustele. | Temporary system error or low battery. | Vajutage nuppu RESET button on the back of the calculator using a thin, pointed object. Ensure battery is good. |
| Valed arvutustulemused. | Incorrect mode selected (e.g., DEG/RAD/GRAD, Normal/Stat), or input error. | Check the current mode settings. Review your input sequence. Perform a RESET kui vaja. |
| Ekraanil kuvatakse teadet "VIGA". | Mathematical error (e.g., division by zero, invalid function argument). | Review the calculation for mathematical validity. Press ON/C vea kustutamiseks. |
