2. Installation
2.1 Installation de la batterie
The Sharp EL-531TH calculator requires one AAA battery for operation. A battery is typically included with the product.
- Repérez le couvercle du compartiment à piles à l'arrière de la calculatrice.
- Retirez le couvercle en suivant le sens indiqué par la flèche.
- Insert one AAA battery, ensuring the correct polarity (+/-) as marked inside the compartment.
- Remettez le couvercle du compartiment à piles en place jusqu'à ce qu'il s'enclenche correctement.
2.2 Mise sous tension initiale
Après avoir installé la batterie, appuyez sur le bouton MARCHE/C key to turn on the calculator. The display should show "0" or a similar initial state. If the display does not appear, recheck the battery installation or replace the battery.

3. Mode d'emploi
3.1 Calculs de base
Enter numbers using the numeric keypad and perform operations using the +, -, ×, ÷ keys. Press = pour obtenir le résultat.
Example: To calculate 15 + 7:
- Presse 1 5
- Presse +
- Presse 7
- Presse = (Résultat : 22)
3.2 Logique algébrique directe (DAL)
The D.A.L. system allows you to input equations exactly as they are written. For example, to calculate sin(30):
- Ensure the calculator is in DEG (degrees) mode. (Press MODE then select DEG if needed).
- Presse péché
- Presse 3 0
- Presse = (Résultat : 0.5)
3.3 touches de fonction
Many keys have secondary functions, accessed by pressing the 2e F key first. The secondary functions are typically printed above the primary key function.
Example: To calculate x² (square of a number):
- Enter the number, e.g., 5
- Presse x² (Résultat : 25)
Example: To calculate √x (square root of a number):
- Presse √
- Enter the number, e.g., 2 5
- Presse = (Résultat : 5)
3.4 Fonctions de mémoire
La calculatrice comprend des fonctions de mémoire permettant de stocker et de rappeler des valeurs.
- STO: Stores the displayed value into a memory variable (A-F, X, Y, M).
- RCL: Recalls a value from a memory variable.
- M+: Ajoute la valeur affichée à la mémoire indépendante.
- M-CLR: Clears the independent memory.
