Научне функције
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 2nd F followed by the key with the desired secondary function.
- Тригонометријске функције: грех, цос, тан and their inverse functions (accessed via 2nd F).
- Логаритамске функције: лог, ln.
- Функције степена и корена: x², √, xʸ.
- Статистика: Enter STAT mode via МОДЕ to perform statistical calculations.
- N-Base Calculations: Perform calculations in binary, octal, decimal, and hexadecimal bases.
Меморијске функције
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 (Store): Stores a value into a memory variable.
- RCL (Recall): Recalls a value from a memory variable.
- М+ / М-: Adds to or subtracts from the independent memory.

Одржавање
Чишћење
Да бисте очистили калкулатор, нежно га обришите меком, сувом крпом. Не користите абразивна средства за чишћење, раствараче или влажне крпе, јер могу оштетити калкулатор.asinг или унутрашње компоненте.
Складиштење
When not in use for extended periods, store the calculator in a cool, dry place away from direct sunlight and extreme temperatures. Keep it in its protective cover to prevent scratches and damage.
Баттери Царе
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.
Решавање проблема
Проблеми са приказом
- Празан екран: Check battery level. Replace the LR44 battery if necessary. Ensure sufficient light for solar operation.
- Слаби екран: This may indicate a low battery. Replace the LR44 battery.
Incorrect Calculations
- Нетачни резултати: 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).
- Порука о грешци: Refer to the calculator's on-screen error codes (if any) for specific issues. Common errors include division by zero or invalid function arguments.
Ресетовање калкулатора
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 СЕТУП menu. Note that resetting may clear all memory and settings.
