Hametraka

Fametrahana bateria

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

1. Ataovy azo antoka fa maty ny kajy.
2. Tadiavo ao ambadiky ny kajy ny fonon'ny fitoeran'ny bateria.
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. Soloy tsara ny fonon'ny efitrefitra bateria.

Hery voalohany On

Tsindrio ny 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 Lojika Aljebraika Mivantana (DAL) system allows you to input elements of an expression in the exact order they appear when written, simplifying complex calculations.

Fampandehanana fototra

• Addition, Subtraction, Multiplication, Division: Ampidiro ny isa ary ampiasao ny +, -, ×, ÷ fanalahidy. mpanao gazety = ho an'ny vokatra.
• Fafao ny fidirana/Fafao ny rehetra: mpanao gazety 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 F faharoa key first, then the desired function key.

• Trigonometric Functions: Ny fahotana, Kosy, tan ary ny fiasa mivadika aminy (arc sin, arc cos, arc tan).
• Asa logaritmika: HIDITRA (logarithma iraisana), ln (logarithma voajanahary).
• Hery sy fakany: x², √, yˣ.
• Factorials: n!
• Reciprocals: 1/x
• Asa hiperbolika: hyp (hyperbolic sine, cosine, tangent).

Fahatsiarovana Functions

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.

Asa statistika

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

1. mpanao gazety MODE hifidy STAT fomba.
2. Choose the desired statistical calculation type (e.g., 1-VAR, 2-VAR).
3. Enter data using the DATA CD fanalahidy.
4. Perform calculations using the statistical function keys.

N-Base Calculations

Perform calculations in Hexadecimal (HEX), Binary (BIN), Decimal (DEC), Octal (OKT), and Pentadecimal (penina) 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.

Home Key

ny an-trano key allows users to return to the initial calculation screen, clearing any previously entered data or settings without turning off the calculator.

FANADIOVANA

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.

Loharanon-kery

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.

Fanamboarana

• Foana na manjavozavo ny fampisehoana: Check battery installation and ensure sufficient light for the solar panel. Replace the AAA battery if necessary.
• Valin'ny kajy diso: 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.
• Tsy mamaly ny tsindry bokotra ny kajy: Ensure the calculator is turned on. If it remains unresponsive, try removing and reinserting the battery, or perform a reset.
