- Remove the old AAA battery (if applicable) and insert a new AAA battery, ensuring correct polarity (+/-).
- Recoloque a tampa do compartimento da bateria e prenda-a com o parafuso.
3.3 Inicialização Inicial
Pressione o LIGADO/C button to turn on the calculator. The display will show the last calculation or be cleared, depending on the previous state.
4. Instruções de operação
4.1 Cálculos básicos
Para realizar operações aritméticas básicas:
- Digite o primeiro número.
- Pressione a tecla de operação desejada (+, -, ×, ÷).
- Digite o segundo número.
- Imprensa = para exibir o resultado.
4.2 EscrevaView Mostrar
A escritaView display permite que você insira e view mathematical expressions as they appear in textbooks. Fractions, roots, and other complex expressions are displayed in a natural format. Use the navigation keys (up, down, left, right arrows) to move the cursor within an expression for editing.
4.3 Function Modes
The calculator offers various modes for different types of calculations. Press the MODO key to cycle through available modes such as:
- NORMAL: For general arithmetic and function calculations.
- STAT: For statistical calculations.
- EQN: For solving equations.

4.4 Funções Científicas
The EL-W531 includes 335 functions. Many functions are accessed directly, while others require pressing the 2º F key first. Common functions include:
- Trigonometric: sin, cos, tan, and their inverse functions (sin-1, porque-1, bronzeado-1).
- Logarithmic/Exponential: log, ln, 10x, ex.
- Power/Root: x2, √, xy, y√x.
- Frações: a b/c key for mixed numbers and improper fractions.
- Memória: STO (store), RCL (recall), M+ (memory plus).
Consult the key labels and the calculator's display for specific function usage.
5. Manutenção
5.1 Limpeza
To clean the calculator, wipe it gently with a soft, dry cloth. Do not use abrasive cleaners, solvents, or wet cloths, as these can damage the casing ou componentes internos.
