Configurar
Fonte de energia
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.
Instalação/Substituição da Bateria
- Certifique-se de que a calculadora esteja desligada.
- Localize a tampa do compartimento da bateria na parte traseira da calculadora.
- Usando uma pequena chave de fenda, remova cuidadosamente o parafuso que prende a tampa da bateria.
- Remove the cover and replace the old LR44 battery with a new one, ensuring correct polarity (+/-).
- Recoloque a tampa da bateria e prenda-a com o parafuso.

Instruções de operação
Ligar/Desligar
- Para ligar: Pressione o LIGADO/C chave.
- Para desligar: Pressione 2º F então DESLIGADO (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.
Operações 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.
- Adição: +
- Subtração: -
- Multiplicação: x
- Divisão: ÷
- É igual a: =
Funções 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 2º F followed by the key with the desired secondary function.
- Funções trigonométricas: pecado, porque, bronzeado and their inverse functions (accessed via 2º F).
- Funções Logarítmicas: registro, ln.
- Funções de energia e raiz: x², √, xʸ.
- Estatísticas: Enter STAT mode via MODO to perform statistical calculations.
- N-Base Calculations: Perform calculations in binary, octal, decimal, and hexadecimal bases.
Funções de memória
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 (Loja): Stores a value into a memory variable.
- RCL (Recall): Recalls a value from a memory variable.
- M+ / M-: Adds to or subtracts from the independent memory.

Manutenção
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.
Armazenar
When not in use for extended periods, store the calculator in a cool, dry place away from direct sunlight and extreme temperatures. Keep it in its protective cover to prevent scratches and damage.
Cuidados com a bateria
If the calculator will not be used for a very long time, it is advisable to remove the LR44 battery to prevent potential leakage and damage to the device.
Solução de problemas
Problemas de exibição
- Tela em branco: Check battery level. Replace the LR44 battery if necessary. Ensure sufficient light for solar operation.
- Exibição fraca: Isso pode indicar bateria fraca. Substitua a bateria LR44.
Cálculos incorretos
- Resultados incorretos: 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).
- Mensagem de erro: Refer to the calculator's on-screen error codes (if any) for specific issues. Common errors include division by zero or invalid function arguments.
Redefinindo a 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 CONFIGURAR menu. Note that resetting may clear all memory and settings.
