2. Podešavanje
2.1 Instalacija baterije
The Sharp EL-531TH calculator requires one AAA battery for operation. A battery is typically included with the product.
- Pronađite poklopac odjeljka za baterije na stražnjoj strani kalkulatora.
- Povucite poklopac u smjeru koji pokazuje strelica.
- Insert one AAA battery, ensuring the correct polarity (+/-) as marked inside the compartment.
- Vratite poklopac pretinca za baterije dok ne klikne sigurno na svoje mjesto.
2.2 Početno uključivanje
Nakon ugradnje baterije, pritisnite ON/C key to turn on the calculator. The display should show "0" or a similar initial state. If the display does not appear, recheck the battery installation or replace the battery.

3. Uputstvo za upotrebu
3.1 Osnovni proračuni
Enter numbers using the numeric keypad and perform operations using the +, -, ×, ÷ keys. Press = da se dobije rezultat.
Example: To calculate 15 + 7:
- Pritisnite 1 5
- Pritisnite +
- Pritisnite 7
- Pritisnite = (Rezultat: 22)
3.2 Direct Algebraic Logic (D.A.L.)
The D.A.L. system allows you to input equations exactly as they are written. For example, to calculate sin(30):
- Ensure the calculator is in DEG (degrees) mode. (Press MODE then select DEG if needed).
- Pritisnite grijeh
- Pritisnite 3 0
- Pritisnite = (Rezultat: 0.5)
3.3 Funkcijski tasteri
Many keys have secondary functions, accessed by pressing the 2. F key first. The secondary functions are typically printed above the primary key function.
Example: To calculate x² (square of a number):
- Enter the number, e.g., 5
- Pritisnite x² (Rezultat: 25)
Example: To calculate √x (square root of a number):
- Pritisnite √
- Enter the number, e.g., 2 5
- Pritisnite = (Rezultat: 5)
3.4 Funkcije memorije
The calculator includes memory functions to store and recall values.
- STO: Stores the displayed value into a memory variable (A-F, X, Y, M).
- RCL: Recalls a value from a memory variable.
- M+: Adds the displayed value to the independent memory.
- M-CLR: Clears the independent memory.

4. Održavanje
4.1 Čišćenje
To clean the calculator, use a soft, dry cloth. For stubborn dirt, slightly dampOperite krpu vodom i blagim deterdžentom, a zatim odmah obrišite suhom krpom. Nemojte koristiti abrazivna sredstva za čišćenje, rastvarače ili prskati direktno na kalkulator.
4.2 Zamjena baterije
When the display becomes dim or calculations are erratic, it is time to replace the battery. Follow the steps in Section 2.1. Ensure the calculator is turned off before replacing the battery.
4.3 Skladištenje

5. Otkrivanje problema
| Problem | Mogući uzrok | Rješenje |
|---|---|---|
| Ekran je prazan ili taman. | Slaba ili mrtva baterija; nepravilna ugradnja baterije. | Zamijenite AAA bateriju, pazeći na ispravan polaritet. |
| Netačni rezultati izračuna. | Incorrect mode setting (e.g., RAD instead of DEG); input error; memory error. | Check the mode setting (DRG key). Review input. Press RESET button (located on the back, requires a thin object like a paperclip) to clear all memory and settings. |
| Tipke ne reagiraju. | Calculator frozen; physical damage. | Pritisnite ON/C. If unresponsive, press the RESET button. If problem persists, contact support. |
| "ERROR" message on display. | Mathematical error (e.g., division by zero, invalid function input). | Review your input and the mathematical operation. Press ON/C da obrišete grešku. |
