2. Navodila za uporabo
2.1 Osnovne aritmetične operacije
Perform basic calculations using the number keys and operation keys (+, -, ×, ÷). Pritisnite = za prikaz rezultata.
- Dodatek: 5 + 3 = (Result: 8)
- odštevanje: 10 - 4 = (Result: 6)
- Množenje: 7 × 2 = (Result: 14)
- Oddelek: 15 ÷ 3 = (Result: 5)
2.2 Znanstvene funkcije
The EL-W531TL offers over 420 scientific functions. Many functions are accessed by pressing the 2. F key followed by the desired function key.
- Trigonometrične funkcije: Uporaba greh, cos, porjavelost keys. For inverse functions, press 2. F then the respective key (e.g., 2. F greh for sin-1).
- Logaritimi: Uporaba dnevnik (osnova 10) in ln (natural logarithm) keys.
- Moči in korenine: Uporaba x² za kvadraturo, √ for square root. For other powers, use yx.
- ulomki: Uporabite ab/c key to enter and calculate fractions.
2.3 Funkcije pomnilnika
The calculator includes independent memory (M) and variable memories (A-F, X, Y).
- Shrani v pomnilnik: Vnesite vrednost in nato pritisnite STO followed by the desired memory key (e.g., STO M+ to store to M).
- Priklic iz spomina: Pritisnite RCL followed by the desired memory key.
- Počisti pomnilnik: Pritisnite M-CLR to clear all memories.
2.4 Izbira načina
Pritisnite NAČIN key to cycle through different calculation modes (e.g., Normal, Stat, Drill). Press CA to change angle units (DEG, RAD, GRAD).

4. Odpravljanje težav
| Težava | Možen vzrok | rešitev |
|---|---|---|
| Zaslon je prazen ali temen. | Prazna ali prazna baterija. | Replace the LR44 battery (see Section 1.1). |
| Napačni rezultati izračuna. | Incorrect mode setting (e.g., RAD instead of DEG). | Check and adjust the angle unit (DEG/RAD/GRAD) using the CA key. Ensure correct input order. |
| Prikazano je sporočilo »NAPAKA«. | Mathematical error (e.g., division by zero, invalid input). | Review your input and calculation steps. Press VKLOP/C da počistite napako. |
| Calculator is unresponsive. | Začasna sistemska napaka. | Pritisnite PONASTAVI button (located on the back, requires a thin object like a paperclip). This will clear all memory and settings. |
