3. Інструкцыя па эксплуатацыі
3.1. Асноўныя аперацыі
- Уключэнне/выключэнне харчавання: Прэса ВКЛ/З to turn on. Press 2-гі Ф затым ВЫКЛ каб выключыць.
- Увод нумара: Use the numeric keys (0-9) and the decimal point key (.) to enter numbers.
- Арыфметычныя аперацыі: Выкарыстоўвайце +, -, ×, ÷ for addition, subtraction, multiplication, and division. Press = выконваць.
- Clear Entry: Прэса ВКЛ/З to clear the current entry.
- Выдаліць: Выкарыстоўвайце DEL клавішу для выдалення апошняй уведзенай лічбы.
3.2. Функцыі
The EL-520TG features 419 functions, accessible directly or via the 2-гі Ф key for secondary functions printed above the keys.
- Direct Algebraic Logic (D.A.L.): Input calculations as they are written, following standard mathematical order of operations.
- Трыганаметрычныя функцыі: Выкарыстоўвайце грэх, cos, загар for sine, cosine, and tangent. Use 2-гі Ф затым sin⁻¹, cos⁻¹, tan⁻¹ for inverse trigonometric functions.
- Лагарыфмічныя функцыі: Выкарыстоўвайце часопіс for common logarithm (base 10) and ln for natural logarithm (base e).
- Функцыі памяці: The calculator has 9 memory registers. Use STO to store a value and RCL to recall a stored value.
- Статыстычныя функцыі: Access statistical modes via РЭЖЫМ. Calculate standard deviation and other statistical values.
- Функцыі ўзвядзення ў ступень і ўзвядзення ў корань: Выкарыстоўвайце x² for square, √ for square root, and yˣ для агульных паўнамоцтваў.
3.3. Рэжымы адлюстравання
Adjust the display format using the НАЛАДЗІЦЬ меню.
- ВЫПРАВІЦЬ: Specifies the number of decimal places.
- SCI: Displays results in scientific notation.
- англійская: Displays results in engineering notation.
- DEG/RAD/GRAD: Selects the angle unit (degrees, radians, or gradians).
4. Тэхнічнае абслугоўванне
4.1. Уборка
Wipe the calculator's exterior with a soft, dry cloth. Do not use abrasive cleaners or solvents, as they may damage the casing або дысплей.
4.2. Замена батарэі
When the display becomes dim or calculations are erratic, it is time to replace the batteries. Refer to the battery compartment cover for the correct battery type and polarity. Ensure the calculator is turned off before replacing batteries.
4.3. Захоўванне
Store the calculator in a cool, dry place, away from direct sunlight and extreme temperatures. Use the provided protective case to prevent scratches and damage to the keys and display.

5. Выпраўленне непаладак
- Пусты або цьмяны дысплей: Праверце ўстаноўку батарэек. Пры неабходнасці заменіце батарэйкі.
- Няправільныя вынікі: Verify the input values and the selected mode (e.g., DEG/RAD). Ensure all previous calculations are cleared.
- Калькулятар не адказвае: Паспрабуйце націснуць СКІД button (usually a small button on the back, requiring a thin object like a paperclip to press). This will clear all memory and settings.
- Паведамленні пра памылкі: Consult the full product manual for specific error code meanings. Common errors include 'ERROR' for mathematical impossibilities (e.g., division by zero) or 'OVERFLOW' for results exceeding the calculator's capacity.
