چمتو کول
د بیټرۍ نصب کول
The Sharp EL-531TGBBW calculator operates on Twin Power (solar and battery). One AAA battery is included. To install or replace the battery:
- ډاډ ترلاسه کړئ چې کیلکولیټر بند دی.
- د کیلکولیټر په شا کې د بیټرۍ د برخې پوښ ومومئ.
- Carefully slide or unscrew the cover to open it.
- Insert the AAA battery, ensuring the correct polarity (+/-) as indicated inside the compartment.
- د بیټرۍ کمپارټ پوښ په خوندي ډول بدل کړئ.
ابتدايي بریښنا فعاله ده
فشار ورکړئ 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.
بنسټیز عملیات
- Addition, Subtraction, Multiplication, Division: شمېرې دننه کړئ او وکاروئ +, -, ×, ÷ کیلي مطبوعاتي = د پایلې لپاره.
- پاکه ننوتنه/ټول پاکه: مطبوعاتي ON/C یو ځل د اوسني ننوتلو د پاکولو لپاره. دوه ځله یې فشار ورکړئ ترڅو ټول محاسبات او حافظه پاکه کړئ (پرته له خپلواک حافظې).
علمي دندې (۲۴۰ دندې)
The calculator supports a wide range of scientific functions. Many keys have secondary functions, accessed by pressing the دوهم ف key first, then the desired function key.
- مثلثیتیک دندې: ګناه, cos, تان او د دوی معکوس دندې (arc sin, arc cos, arc tan).
- لوګاریتمیک دندې: ننوتل (common logarithm), ln (طبیعي لوګاریتم).
- ځواکونه او ریښې: x², √, yˣ.
- Factorials: n!
- Reciprocals: 1/x
- هایپربولیک دندې: هایپ (hyperbolic sine, cosine, tangent).
د حافظې دندې
The calculator includes eight temporary memories, one independent memory (M+, M-, RCL M), and one last answer memory (ANS).
- STO (دوکان): Stores a value into a variable (A-F, X, Y).
- آر سي ایل (یادونه): د متغیر څخه ارزښت بیرته راګرځوي.
- M+ / M-: ښودل شوی ارزښت له خپلواک حافظې څخه اضافه/کموي.
- ځواب: Recalls the result of the previous calculation.
احصایوي دندې
The calculator supports 1-variable and 2-variable statistics, along with six regression types.
- مطبوعاتي موډ غوره کول STAT حالت
- Choose the desired statistical calculation type (e.g., 1-VAR, 2-VAR).
- Enter data using the DATA CD کلید
- Perform calculations using the statistical function keys.
N-Base Calculations
Perform calculations in Hexadecimal (هیکس), Binary (BIN), Decimal (DEC), Octal (OCT), and Pentadecimal (قلم) 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.
د کور کیلي
د کور key allows users to return to the initial calculation screen, clearing any previously entered data or settings without turning off the calculator.

ساتنه
پاکول
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.
د بریښنا سرچینه
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.
د ستونزو حل کول
- ښودنه خالي یا تیاره ده: Check battery installation and ensure sufficient light for the solar panel. Replace the AAA battery if necessary.
- د ناسمې محاسبې پایلې: 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.
