2. Mise en route

2.1. Installation de la batterie

The Sharp EL501X2BWH calculator operates on two LR44 batteries (included). To install or replace batteries:

1. Assurez-vous que la calculatrice est éteinte.
2. Repérez le couvercle du compartiment à piles à l'arrière de la calculatrice.
3. Remove the cover using a small screwdriver.
4. Insert two new LR44 batteries, observing the correct polarity (+/-).
5. Replacez soigneusement le couvercle du compartiment à piles.

Note: Utilisez toujours des piles neuves et jetez les piles usagées de manière responsable.

2.2. Allumer et éteindre

• Pour allumer la calculatrice, appuyez sur MARCHE/C bouton.
• To turn off the calculator, press the 2e F bouton suivi du DÉSACTIVÉ bouton.

2.3. Afficher plusview

The calculator features a 10-digit, 1-line LCD display. Indicators for various modes (e.g., DEG, RAD, GRAD, CPLX, STAT) will appear on the display to show the current calculator state.

3. Opérations de base

3.1. Arithmetic Calculations

Perform basic arithmetic operations using the number keys and the +, -, ×, et ÷ clés. Presse = pour afficher le résultat.

• Example: To calculate 15 + 7: Press 1 5 + 7 =. L'écran affichera 22.

3.2. Clear Functions

• Presse CE to clear the last entered number or operation.
• Presse MARCHE/C to clear all entries and reset the calculator to its initial state (except memory).

4. Fonctions scientifiques

The calculator provides 131 built-in functions. Many keys have secondary functions, accessed by pressing the 2e F touche avant la touche de fonction souhaitée.

4.1. Trigonometric Functions

Utiliser péché, parce que, tanné for standard trigonometric calculations. Their inverse functions (péché^-1, parce que^-1, tanné^-1) sont accessibles via 2e F.

The angle unit can be changed using the DRG touche. Appuyez sur DRG repeatedly to cycle through DEG (degrees), RAD (radians), and GRAD (gradients).

4.2. Logarithmic and Exponential Functions

• Logarithmes : Utiliser enregistrer (base 10) et ln (logarithme naturel).
• Exponentials: Utiliser 10^x (accessed via 2e F et enregistrer) et e^x (accessed via 2e F et ln).

4.3. Powers and Roots

• Carré: Utiliser x².
• Racine carrée: Utiliser √ (accessed via 2e F et x²).
• Pouvoir général : Utiliser y^x.
• Reciprocal: Utiliser 1/x (accessed via 2e F et y^x).

4.4. Factorials

Calculate factorials using the n! function (accessed via 2e F et CPLX).

5. Fonctions avancées

5.1. N-Base Calculations (HEX, DEC, BIN, OCT)

The calculator supports calculations in different number bases: hexadecimal (HEX), decimal (DEC), binary (BIN), and octal (OCT). Use the dedicated keys for these operations, typically found above the number keys (e.g., →OCT, →BIN, →DEC, →HEX).

5.2. Complex Number Calculations

To enter and perform calculations with complex numbers, switch to Complex Mode. Press CPLX to activate this mode. The display will show "CPLX".

Refer to the calculator's key markings for specific complex number operations (e.g., real and imaginary part extraction, argument, magnitude).

5.3. Statistics Functions

The calculator supports one-variable statistical calculations. To enter Statistics Mode, press STAT. The display will show "STAT".

Utilisez le DATA CD key to clear statistical data and the M+ key to input data points. Statistical results (mean, standard deviation, etc.) can be retrieved using specific function keys, often accessed via 2e F.

5.4. Fonctions de mémoire

The calculator has one independent memory. Use the following keys:

• M+: Ajoute la valeur affichée à la mémoire.
• STO: Stores the displayed value into memory.
• RCL: Recalls the value from memory to the display.

6. Maintenance et entretien

6.1. Nettoyage

To clean the calculator, wipe it with a soft, dry cloth. Do not use abrasive cleaners, solvents, or spray directly onto the calculator, as this may damage the casing ou composants internes.

6.2. Stockage

When not in use, store the calculator in its protective hardcover to prevent scratches and damage. Avoid exposing the calculator to extreme temperatures, humidity, or direct sunlight for extended periods.

7. Dépannage

7.1. Problèmes courants

• La calculatrice ne s'allume pas : Vérifiez l'installation des piles et assurez-vous qu'elles ne sont pas déchargées. Remplacez-les si nécessaire.
• "Error" message displayed: This usually indicates an invalid operation (e.g., division by zero, taking the square root of a negative number). Press CE or MARCHE/C to clear the error and re-enter the calculation.
• Résultats incorrects : Verify that the correct mode (DEG/RAD/GRAD, Normal/Stat/Complex) is selected for your calculation. Ensure all previous calculations are cleared using MARCHE/C before starting a new one.

7.2. Resetting the Calculator

If the calculator behaves erratically or freezes, a reset may resolve the issue. Locate the RÉINITIALISER button (a small recessed button, often requiring a thin object like a paperclip to press) on the back or front panel. Pressing this button will clear all memory and settings, returning the calculator to its factory default state.
