The Sharp EL-531TGBBW calculator operates on Twin Power (solar and battery). One AAA battery is included. To install or replace the battery:

1. ගණක යන්ත්‍රය ක්‍රියා විරහිත කර ඇති බවට වග බලා ගන්න.
2. කැල්කියුලේටරයේ පිටුපස බැටරි මැදිරි කවරය සොයා ගන්න.
3. Carefully slide or unscrew the cover to open it.
4. Insert the AAA battery, ensuring the correct polarity (+/-) as indicated inside the compartment.
5. බැටරි මැදිරි ආවරණය ආරක්ෂිතව ප්රතිස්ථාපනය කරන්න.

මුලික බලය සක්රිය

ඔබන්න 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.

මූලික මෙහෙයුම්

• Addition, Subtraction, Multiplication, Division: අංක ඇතුළත් කර භාවිතා කරන්න +, -, ×, ÷ යතුරු ඔබන්න = ප්‍රතිඵලය සඳහා.
• ඇතුල්වීම හිස් කරන්න/සියල්ල හිස්: ඔබන්න 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 2 වන එෆ් පළමුව යතුර, පසුව අපේක්ෂිත ක්‍රියාකාරී යතුර.

• ත්‍රිකෝණමිතික කාර්යයන්: පව්, cos, tan සහ ඒවායේ ප්‍රතිලෝම ශ්‍රිත (arc sin, arc cos, arc tan).
• ලඝුගණක ශ්‍රිත: ලඝු-සටහන (common logarithm), ln (ස්වාභාවික ලඝුගණකය).
• බලතල සහ මූලයන්: x² ප්‍රමාණය, √ අයිතමය, yˣ.
• සාධක: n!
• Reciprocals: 1/x
• හයිපර්බෝලික් ශ්‍රිත: හයිප් (hyperbolic sine, cosine, tangent).

මතක කාර්යයන්

The calculator includes eight temporary memories, one independent memory (M+, M-, ආර්සීඑල් එම්), 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.
• පිළිතුර: Recalls the result of the previous calculation.

සංඛ්‍යානමය කාර්යයන්

The calculator supports 1-variable and 2-variable statistics, along with six regression types.

1. ඔබන්න මාදිලිය තෝරා ගැනීමට STAT මාදිලිය.
2. Choose the desired statistical calculation type (e.g., 1-VAR, 2-VAR).
3. Enter data using the DATA CD යතුර.
4. Perform calculations using the statistical function keys.

N-Base Calculations

Perform calculations in Hexadecimal (හෙක්ස්), Binary (BIN), Decimal (DEC), Octal (ඔක්), and Pentadecimal (PEN) 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.

නඩත්තු කිරීම

පිරිසිදු කිරීම

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.

බලශක්ති ප්රභවය

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.

දෝෂගවේෂණය

• සංදර්ශකය හිස් හෝ අඳුරු ය: Check battery installation and ensure sufficient light for the solar panel. Replace the AAA battery if necessary.
• වැරදි ගණනය කිරීමේ ප්‍රතිඵල: Verify the input sequence and selected mode (e.g., DEG/RAD/GRAD, Normal/STAT). Press යළි පිහිටුවන්න (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.
