Navodila za uporabo

Osnovne operacije

• Aritmetika: Vnesite številke in uporabite +, -, ×, ÷ ključi. Pritisnite = za rezultat.
• Počisti vnos/Vse počisti: Pritisnite VKLOP/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 2. 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 (število obdobij), I/Y (interest rate per year), PV (sedanja vrednost), PMT (plačilo) in FV (future value).

1. Setting P/Y (Payments per Year): Pritisnite 2. F potem P/L. 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, PMT, oz 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 PMT.

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 NPV in IRR functions (accessed via 2. F).

Amortizacija

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

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

Statistični izračuni

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

Pomnilniške funkcije

• M+: Prikazano vrednost doda v neodvisni pomnilnik.
• M-: Odšteje prikazano vrednost od neodvisnega pomnilnika.
• RCL: Prikliče vrednost iz spomina.
• STO: Stores the displayed value into a specific memory register.
• M-CLR: Clears the independent memory (likely 2. F + M-CLR).

Nastavitve načina

Pritisnite NAČIN key to access different calculation modes (e.g., COMP for normal calculations, STAT for statistics). Use the arrow keys to navigate and ORL izbrati.

Vzdrževanje

Čiščenje

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

Shranjevanje

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.

Odpravljanje težav

• Zaslon je prazen ali zatemnjen: Preverite namestitev baterij. Po potrebi zamenjajte baterijo CR2032.
• Error message (e.g., "ERROR"): This usually indicates an invalid operation or input. Press VKLOP/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.
