The Sharp EL-738XTB requires one CR2032 battery. To install or replace the battery:
- Ensure the calculator is turned OFF.
- Localize a tampa do compartimento da bateria na parte traseira da calculadora.

- Recoloque a tampa do compartimento da bateria e prenda-a com o parafuso.
Ligação inicial
Pressione o LIGADO/C key to turn on the calculator. The display should show "0." or similar. If the display is dim or blank, check the battery installation.
Instruções de operação
Operações básicas
- Aritmética: Insira os números e use o +, -, ×, ÷ chaves. Imprensa = pelo resultado.
- Clear Entry/All Clear: Imprensa LIGADO/C once to clear the current entry. Press it twice to clear all calculations and memory (except independent memory).
- Second Function: Many keys have a second function, indicated above the key. Press 2º F then the desired key to access its second function.
Financial Functions (TVM)
The calculator is equipped with Time Value of Money (TVM) functions for financial calculations. The primary TVM keys are N (número de períodos), I/Y (interest rate per year), PV (valor presente), TPM (pagamento), e FV (future value).
- Setting P/Y (Payments per Year): Imprensa 2º F então P/S. Enter the desired number of payments per year (e.g., 12 for monthly) and press Otorrinolaringologista.
- Inputting Values: Enter a numerical value, then press the corresponding TVM key (N, I/Y, PV, TPM, ou FV) to store it.
- Calculating Unknown: After inputting at least four of the five TVM variables, press the key for the unknown variable to calculate its value. For example, to find PMT, input N, I/Y, PV, FV, then press TPM.
Amortization Calculation
To calculate amortization schedules, use the AMRT function. This typically follows a TVM calculation where a loan is defined.
Cash Flow Analysis (NPV, IRR)
The calculator supports cash flow analysis using Net Present Value (NPV) and Internal Rate of Return (IRR). Use the CFi (Cash Flow Input) and COMP (Compute) keys in conjunction with the VPL e TIR functions (accessed via 2º F).
Depreciação
The calculator offers three different methodologies for depreciation calculation. Refer to the DEPR key and its associated second functions for detailed steps.
Breakeven, Profit, and Percent Difference
Utilize o BRKV key for breakeven analysis and other related functions for profit and percent difference calculations.
Cálculos Estatísticos
The EL-738XTB can perform 1-variable and 2-variable statistics. Enter data points using the DADOS function (likely 2º F + Otorrinolaringologista) and then use the statistical keys like Σx, Σx², n, x̄, σx, etc., to compute results.
Funções de memória
- M+: Adiciona o valor exibido à memória independente.
- M-: Subtrai o valor exibido da memória independente.
- RCL: Recalls the value from memory.
- STO: Stores the displayed value into a specific memory register.
- M-CLR: Clears the independent memory (likely 2º F + M-CLR).
Configurações de modo
Pressione o MODO key to access different calculation modes (e.g., COMP for normal calculations, STAT for statistics). Use the arrow keys to navigate and Otorrinolaringologista para selecionar.
Manutenção
Limpeza
