- Pentru a opri: Apăsați A doua linie de atac apoi OFF (usually located above the ON/C key).
Display Modes (WriteView / Line)
The calculator features a WriteView display that shows fractions, roots, and formulas as they appear in textbooks. You can switch to a traditional line mode if preferred.
- To toggle between WriteView and Line mode: Press MOD and select the desired display option. Refer to the on-screen menu for specific selections.
Operații aritmetice de bază
Enter numbers and operations in sequence. The D.A.L. (Direct Algebraic Logic) input method allows you to input equations exactly as they are written.
- Plus: +
- Scădere: -
- Multiplicare: x
- Diviziune: ÷
- Egal cu: =
Funcții științifice
The calculator includes 414 pre-programmed functions covering statistics, n-base calculations, logical operators, trigonometry, logarithms, and more. Access these functions using the dedicated keys or by pressing A doua linie de atac followed by the key with the desired secondary function.
- Funcții trigonometrice: păcat, cos, bronzat and their inverse functions (accessed via A doua linie de atac).
- Funcții logaritmice: jurnal, ln.
- Funcții de putere și rădăcină: x², √, xʸ.
- Statistici: Enter STAT mode via MOD to perform statistical calculations.
- N-Base Calculations: Perform calculations in binary, octal, decimal, and hexadecimal bases.
Funcții de memorie
The calculator features 4 shortcut memory buttons (D1, D2, D3, D4) for quick access to frequently used functions or constants. Additionally, standard memory functions (M+, M-, RCL, STO) are available.
- STO (Magazin): Stores a value into a memory variable.
- RCL (Rechemare): Recalls a value from a memory variable.
- M+ / M-: Adds to or subtracts from the independent memory.

If the calculator will not be used for a very long time, it is advisable to remove the LR44 battery to prevent potential leakage and damage to the device.
Depanare
Probleme de afișare
- Afișaj gol: Check battery level. Replace the LR44 battery if necessary. Ensure sufficient light for solar operation.
- Afișaj slab: Acest lucru poate indica o baterie descărcată. Înlocuiți bateria LR44.
Calcule incorecte
- Rezultate incorecte: Verify the input method (D.A.L.) and ensure all values are entered correctly. Check if the calculator is in the correct mode (e.g., DEG/RAD for trigonometric functions, STAT mode for statistics).
- Mesaj de eroare: Refer to the calculator's on-screen error codes (if any) for specific issues. Common errors include division by zero or invalid function arguments.
Resetarea calculatorului
If the calculator behaves erratically or freezes, a reset may resolve the issue. Locate the small reset button (often on the back or side, requiring a thin object like a paperclip to press) or perform a soft reset via the ÎNFIINȚAT menu. Note that resetting may clear all memory and settings.
