Enstalasyon

Enstalasyon batri

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

1. Asire w ke kalkilatris la etenn.
2. Jwenn kouvèti konpatiman pil la sou dèyè kalkilatris la.
3. Carefully slide or unscrew the cover to open it.
4. Mete pil AAA a nan plas li, asire w ke polarite a kòrèk (+/-) jan yo endike anndan konpatiman an.
5. Ranplase kouvèti lòj batri a byen.

Premye pouvwa sou

Peze a 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.

Enstriksyon Operasyon

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.

Operasyon debaz yo

• Addition, Subtraction, Multiplication, Division: Enter numbers and use the +, -, ×, ÷ kle. Peze = pou rezilta a.
• Clear Entry/All Clear: Peze 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 2yèm F key first, then the desired function key.

• Fonksyon trigonometrik: peche, kos, tan and their inverse functions (arc sin, arc cos, arc tan).
• Fonksyon Logaritmik: boutèy demi lit (common logarithm), ln (natural logarithm).
• Powers and Roots: x², √, yˣ.
• Factorials: n!
• Reciprocals: 1/x
• Fonksyon ipèbolik: hyp (hyperbolic sine, cosine, tangent).

Fonksyon memwa

The calculator includes eight temporary memories, one independent memory (M+, M-, RCL M), and one last answer memory (ANS).

• STO (Magazen): Stores a value into a variable (A-F, X, Y).
• RCL (Rapèl): Raple yon valè nan yon varyab.
• M+ / M-: Ajoute/soustrè valè ki parèt la nan/nan memwa endepandan an.
• ANS: Recalls the result of the previous calculation.

Statistical Functions

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

1. Peze MÒD pou chwazi STAT mòd.
2. Choose the desired statistical calculation type (e.g., 1-VAR, 2-VAR).
3. Enter data using the DATA CD kle.
4. Perform calculations using the statistical function keys.

N-Base Calculations

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

Kle Kay

La LAKAY key allows users to return to the initial calculation screen, clearing any previously entered data or settings without turning off the calculator.

Antretyen

Netwayaj

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.

Sous pouvwa

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.

Depanaj

• Ekran an vid oswa li pa klere byen: Check battery installation and ensure sufficient light for the solar panel. Replace the AAA battery if necessary.
• Rezilta kalkil ki pa kòrèk: 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.
