Înființat

Instalarea bateriei

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

1. Asigurați-vă că calculatorul este oprit.
2. Localizați capacul compartimentului bateriilor de pe spatele calculatorului.
3. Carefully slide or unscrew the cover to open it.
4. Introduceți bateria AAA, asigurându-vă că polaritatea este corectă (+/-), așa cum este indicată în interiorul compartimentului.
5. Puneți bine capacul compartimentului bateriei.

Pornirea inițială

Apăsați tasta 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 Logică algebrică directă (DAL) system allows you to input elements of an expression in the exact order they appear when written, simplifying complex calculations.

Operații de bază

• Addition, Subtraction, Multiplication, Division: Introduceți numere și utilizați +, -, ×, ÷ chei. presa = pentru rezultat.
• Ștergere intrare/Ștergere totală: Presa ON/C o dată pentru a șterge intrarea curentă. Apăsați de două ori pentru a șterge toate calculele și memoria (cu excepția memoriei independente).

Scientific Functions (273 Functions)

The calculator supports a wide range of scientific functions. Many keys have secondary functions, accessed by pressing the A doua linie de atac key first, then the desired function key.

• Funcții trigonometrice: păcat, cos, bronzat și funcțiile lor inverse (arc sin, arc cos, arc tan).
• Funcții logaritmice: jurnal (logaritm comun), ln (logaritm natural).
• Puteri și rădăcini: x², √, yˣ.
• Factorials: n!
• Reciprocals: 1/x
• Funcții hiperbolice: hiperactivitate (hyperbolic sine, cosine, tangent).

Funcții de memorie

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 (Rechemare): 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.

Statistical Functions

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

1. Presa MOD pentru a selecta STAT modul.
2. Choose the desired statistical calculation type (e.g., 1-VAR, 2-VAR).
3. Enter data using the CD de date cheie.
4. Perform calculations using the statistical function keys.

N-Base Calculations

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

Tasta Acasă

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

Întreţinere

Curatenie

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.

Sursa de alimentare

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.

Depanare

• Afișajul este gol sau slab iluminat: Check battery installation and ensure sufficient light for the solar panel. Replace the AAA battery if necessary.
• Rezultate incorecte ale calculului: 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.
