Installazione della batteria

The Sharp EL-738XTB requires one CR2032 battery. To install or replace the battery:

1. Assicurarsi che la calcolatrice sia SPENTA.
2. Individuare il coperchio del vano batterie sul retro della calcolatrice.
3. Utilizzare un piccolo cacciavite per rimuovere la vite che fissa il coperchio, quindi far scorrere il coperchio verso l'esterno.
4. Remove the old battery (if applicable) and insert a new CR2032 battery with the positive (+) side facing up.
5. Riposizionare il coperchio del vano batteria e fissarlo con la vite.

Accensione iniziale

Premere il tasto ACCESO/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.

Istruzioni per l'uso

Operazioni di base

• Aritmetica: Inserisci i numeri e usa il +, -, ×, ÷ chiavi. Premere = per il risultato.
• Ingresso libero/Tutto libero: Premere ACCESO/C una volta per cancellare l'immissione corrente. Premerlo due volte per cancellare tutti i calcoli e la memoria (tranne la memoria indipendente).
• Second Function: Many keys have a second function, indicated above the key. Press 2° piano 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 (number of periods), I/Y (interest rate per year), PV (present value), Previsione temporale (payment), and FV (future value).

1. Setting P/Y (Payments per Year): Premere 2° piano Poi P/Y. Enter the desired number of payments per year (e.g., 12 for monthly) and press ORL.
2. Inputting Values: Enter a numerical value, then press the corresponding TVM key (N, I/Y, PV, Previsione temporale, O FV) to store it.
3. 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 Previsione temporale.

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 VAN E Tasso di rendimento interno functions (accessed via 2° piano).

Ammortamento

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

Utilizzare il BRKV key for breakeven analysis and other related functions for profit and percent difference calculations.

Calcoli statistici

The EL-738XTB can perform 1-variable and 2-variable statistics. Enter data points using the DATI function (likely 2° piano + ORL) and then use the statistical keys like Six, Σx², n, x̄, si, etc., to compute results.

Funzioni di memoria

• M+: Aggiunge il valore visualizzato alla memoria indipendente.
• M-: Sottrae il valore visualizzato dalla memoria indipendente.
• RCL: Recalls the value from memory.
• STO: Stores the displayed value into a specific memory register.
• M-CLR: Clears the independent memory (likely 2° piano + M-CLR).

Impostazioni della modalità

Premere il tasto MODALITÀ key to access different calculation modes (e.g., COMP for normal calculations, STAT for statistics). Use the arrow keys to navigate and ORL per selezionare.

Manutenzione

Pulizia

Wipe the calculator with a soft, dry cloth. Do not use abrasive cleaners or solvents, as they may damage the casing o display.

Magazzinaggio

Store the calculator in a cool, dry place away from direct sunlight and extreme temperatures. If storing for an extended period, it is recommended to remove the battery to prevent leakage.

Risoluzione dei problemi

• Il display è vuoto o poco luminoso: Controllare l'installazione della batteria. Sostituire la batteria CR2032 se necessario.
• Error message (e.g., "ERROR"): This usually indicates an invalid operation or input. Press ACCESO/C to clear the error and re-enter your calculation. Review the specific function's input requirements.
• Calculator not responding: Try turning the calculator OFF and then ON again. If the issue persists, remove the battery for a few minutes, then reinsert it.
