If the display is blank or shows unusual characters, ensure the battery is correctly installed and try pressing the RÉINITIALISER button (usually a small recessed button requiring a thin object like a paperclip).
Mode d'emploi
1. Basic Arithmetic Operations
Enter numbers and operations in the order they appear. The Direct Algebraic Logic (D.A.L.) system allows for natural input.
- Ajout: [Number 1] [+] [Number 2] [=]
- Soustraction: [Number 1] [-] [Number 2] [=]
- Multiplication: [Number 1] [x] [Number 2] [=]
- Division: [Number 1] [÷] [Number 2] [=]
2. Function Keys Overview
The calculator features a wide array of function keys. Many keys have secondary functions, accessed by pressing the 2e F key first, indicated by text above the primary key function.

Fonctions trigonométriques
Utiliser péché, parce que, tanné pour le sinus, le cosinus et la tangente. Fonctions inverses (péché-1, parce que-1, tanné-1) sont accessibles via 2e F.
Fonctions logarithmiques et exponentielles
Keys include enregistrer (common logarithm), ln (natural logarithm), 10x, et ex.
Power and Root Functions
Utiliser x2, x3, √ (square root), and 3√ (cube root).
Fonctions de mémoire
The calculator has 8 temporary memory buttons. Use STO (Store) to save a value and RCL (Recall) to retrieve it.
Calculs statistiques
To enter statistical mode, press MODE puis sélectionnez STAT. The calculator supports 1 and 2 variable statistics. Refer to the on-screen prompts for data entry and calculation of statistical values like mean, standard deviation, etc.
3. Sélection du mode
Appuyez sur le MODE key to switch between Normal and Statistical modes. Ensure you are in the correct mode for your calculations.
Entretien
1. Nettoyage
To clean the calculator, gently wipe the surface with a soft, dry cloth. For stubborn dirt, a slightly damp cloth can be used, but ensure no liquid enters the calculator. Do not use abrasive cleaners or solvents.
2. Stockage
