2. Instrucciones de funcionamiento
2.1 Operaciones aritméticas básicas
Perform basic calculations using the number keys and operation keys (+, -, ×, ÷). Prensa = para mostrar el resultado.
- Suma: 5 + 3 = (Resultado: 8)
- Sustracción: 10 - 4 = (Resultado: 6)
- Multiplicación: 7 × 2 = (Resultado: 14)
- División: 15 ÷ 3 = (Resultado: 5)
2.2 Funciones científicas
The EL-W531TL offers over 420 scientific functions. Many functions are accessed by pressing the 2do F tecla seguida de la tecla de función deseada.
- Funciones trigonométricas: Usar pecado, porque, broncearse keys. For inverse functions, press 2do F then the respective key (e.g., 2do F pecado for sin-1).
- Logaritmos: Usar registro (base 10) y ln Claves (logaritmo natural).
- Poderes y raíces: Usar x² para cuadrar, √ for square root. For other powers, use yx.
- Fracciones: Utilice el abecedario key to enter and calculate fractions.
2.3 Funciones de memoria
The calculator includes independent memory (M) and variable memories (A-F, X, Y).
- Guardar en memoria: Enter a value, then press STO followed by the desired memory key (e.g., STO M+ to store to M).
- Recordar de memoria: Prensa LCR followed by the desired memory key.
- Memoria clara: Prensa M-CLR to clear all memories.
Selección de 2.4 modos
Presione el MODO key to cycle through different calculation modes (e.g., Normal, Stat, Drill). Press CA to change angle units (DEG, RAD, GRAD).

4. Solución de problemas
| Problema | Posible causa | Solución |
|---|---|---|
| La pantalla está en blanco o tenue. | Batería baja o muerta. | Reemplace la batería LR44 (consulte la Sección 1.1). |
| Resultados de cálculo incorrectos. | Incorrect mode setting (e.g., RAD instead of DEG). | Check and adjust the angle unit (DEG/RAD/GRAD) using the CA key. Ensure correct input order. |
| Se muestra el mensaje "ERROR". | Mathematical error (e.g., division by zero, invalid input). | Review your input and calculation steps. Press ENCENDIDO/C para borrar el error. |
| La calculadora no responde. | Fallo temporal del sistema. | Presione el REINICIAR button (located on the back, requires a thin object like a paperclip). This will clear all memory and settings. |
