Configuración
Fuente de poder
The Sharp EL-W531TG-WH calculator operates using both solar power and a backup battery (1 LR44 battery included). The solar panel provides power in well-lit environments, while the battery ensures operation in low-light conditions.
Instalación/reemplazo de la batería
- Asegúrese de que la calculadora esté apagada.
- Localice la tapa del compartimiento de la batería en la parte posterior de la calculadora.
- Con un destornillador pequeño, retire con cuidado el tornillo que fija la tapa de la batería.
- Remove the cover and replace the old LR44 battery with a new one, ensuring correct polarity (+/-).
- Vuelva a colocar la tapa de la batería y asegúrela con el tornillo.

- Para encender: Presione el ENCENDIDO/C llave.
- Para apagar: Presione 2do F entonces APAGADO (usually located above the ON/C key).
Display Modes (WriteView / Line)
The calculator features a WriteView display that shows fractions, roots, and formulas as they appear in textbooks. You can switch to a traditional line mode if preferred.
- To toggle between WriteView and Line mode: Press MODO and select the desired display option. Refer to the on-screen menu for specific selections.
Operaciones aritméticas básicas
Enter numbers and operations in sequence. The D.A.L. (Direct Algebraic Logic) input method allows you to input equations exactly as they are written.
- Suma: +
- Sustracción: -
- Multiplicación: x
- División: ÷
- Es igual a: =
Funciones científicas
The calculator includes 414 pre-programmed functions covering statistics, n-base calculations, logical operators, trigonometry, logarithms, and more. Access these functions using the dedicated keys or by pressing 2do F followed by the key with the desired secondary function.
- Funciones trigonométricas: pecado, porque, broncearse and their inverse functions (accessed via 2do F).
- Funciones logarítmicas: registro, ln.
- Funciones de potencia y raíz: x², √, xʸ.
- Estadística: Enter STAT mode via MODO to perform statistical calculations.
- N-Base Calculations: Perform calculations in binary, octal, decimal, and hexadecimal bases.
Funciones de la memoria
The calculator features 4 shortcut memory buttons (D1, D2, D3, D4) for quick access to frequently used functions or constants. Additionally, standard memory functions (M+, M-, RCL, STO) are available.
- STO (Tienda): Stores a value into a memory variable.
- RCL (Retiro): Recalls a value from a memory variable.
- M+ / M-: Adds to or subtracts from the independent memory.

Solución de problemas
Problemas de visualización
- Pantalla en blanco: Check battery level. Replace the LR44 battery if necessary. Ensure sufficient light for solar operation.
- Pantalla débil: Esto podría indicar que la batería está baja. Reemplace la batería LR44.
Cálculos incorrectos
- Resultados incorrectos: Verify the input method (D.A.L.) and ensure all values are entered correctly. Check if the calculator is in the correct mode (e.g., DEG/RAD for trigonometric functions, STAT mode for statistics).
- Mensaje de error: Refer to the calculator's on-screen error codes (if any) for specific issues. Common errors include division by zero or invalid function arguments.
Reiniciar la calculadora
If the calculator behaves erratically or freezes, a reset may resolve the issue. Locate the small reset button (often on the back or side, requiring a thin object like a paperclip to press) or perform a soft reset via the CONFIGURACIÓN menu. Note that resetting may clear all memory and settings.
