Жайгашуу
Батарея орнотуу
The Sharp EL-531TGBBW calculator operates on Twin Power (solar and battery). One AAA battery is included. To install or replace the battery:
- Калькулятор өчүрүлгөнүн текшериңиз.
- Калькулятордун артындагы батарея бөлүкчөсүнүн капкагын табыңыз.
- Carefully slide or unscrew the cover to open it.
- Insert the AAA battery, ensuring the correct polarity (+/-) as indicated inside the compartment.
- Батарея бөлүкчөсүнүн капкагын бекем орнотуңуз.
Баштапкы күйгүзүү
басыңыз ON/C key to turn on the calculator. The display should show '0' or a previous calculation result. If the display is dim or blank, ensure the battery is correctly installed and that there is sufficient light for the solar panel.

Display and Direct Algebraic Logic (D.A.L.)
The calculator features a 2-line LCD display, showing both the calculation entry and the result simultaneously. The Direct Algebraic Logic (D.A.L.) system allows you to input elements of an expression in the exact order they appear when written, simplifying complex calculations.
Негизги операциялар
- Кошуу, кемитүү, көбөйтүү, бөлүү: Сандарды киргизип, колдонуңуз +, -, ×, ÷ ачкычтар. Басыңыз = натыйжа үчүн.
- Clear Entry/All Clear: Басыңыз ON/C once to clear the current entry. Press it twice to clear all calculations and memory (except independent memory).
Scientific Functions (273 Functions)
The calculator supports a wide range of scientific functions. Many keys have secondary functions, accessed by pressing the 2nd F key first, then the desired function key.
- Тригонометриялык функциялар: күнөө, cos, тан жана алардын тескери функциялары (arc sin, arc cos, arc tan).
- Логарифмдик функциялар: журнал (common logarithm), ln (натурал логарифм).
- Күчтөр жана тамырлар: x², √, yˣ.
- Factorials: n!
- Reciprocals: 1/x
- Гиперболикалык функциялар: hyp (hyperbolic sine, cosine, tangent).
Эс тутум функциялары
The calculator includes eight temporary memories, one independent memory (M+, M-, RCL M), and one last answer memory (ANS).
- STO (Store): Stores a value into a variable (A-F, X, Y).
- RCL (Recall): Recalls a value from a variable.
- M+ / M-: Adds/subtracts the displayed value to/from the independent memory.
- ANS: Recalls the result of the previous calculation.
Статистикалык функциялар
The calculator supports 1-variable and 2-variable statistics, along with six regression types.
- Басыңыз РЕЖИМ тандоо үчүн STAT режими.
- Choose the desired statistical calculation type (e.g., 1-VAR, 2-VAR).
- Enter data using the DATA CD ачкыч.
- Perform calculations using the statistical function keys.
N-Base Calculations
Perform calculations in Hexadecimal (HEX), Binary (БИН), Decimal (ДЕК), Octal (OCT), and Pentadecimal (ПЕН) bases.
- Use the dedicated keys for base conversions (e.g., →HEX, →BIN).
- Logical operations like AND, OR, NOT, XOR, and XNOR are also available.
Equation Editing & Playback
The calculator allows for editing previously entered equations and multi-line playback. Use the arrow keys to navigate through entries and make corrections.
Үй ачкычы
The ҮЙ key allows users to return to the initial calculation screen, clearing any previously entered data or settings without turning off the calculator.

Техникалык тейлөө
Тазалоо
To clean the calculator, use a soft, dry cloth. Do not use abrasive cleaners, solvents, or spray directly onto the calculator. Avoid excessive moisture.
Protective Hard Cover
The calculator comes with a protective hard cover. Always use this cover when the calculator is not in use to prevent scratches, dust accumulation, and accidental damage to the display and keys.
Power Source
The EL-531TGBBW utilizes Twin Power, meaning it operates on both solar energy and a AAA battery. Ensure the solar panel is exposed to light for optimal performance and to extend battery life. Replace the AAA battery when the display becomes dim or unresponsive in low light conditions.
Проблемаларды чечүү
- Дисплей бош же күңүрт: Check battery installation and ensure sufficient light for the solar panel. Replace the AAA battery if necessary.
- Туура эмес эсептөө натыйжалары: Verify the input sequence and selected mode (e.g., DEG/RAD/GRAD, Normal/STAT). Press RESET (located on the back, may require a thin object like a paperclip) to return the calculator to its default settings. Note that resetting will clear all memory contents.
- Calculator does not respond to key presses: Ensure the calculator is turned on. If it remains unresponsive, try removing and reinserting the battery, or perform a reset.
