2. Seadistamine
2.1 Aku paigaldamine
The Sharp EL-531TH calculator requires one AAA battery for operation. A battery is typically included with the product.
- Leidke kalkulaatori tagaküljel olev patareipesa kate.
- Libistage kate noolega näidatud suunas ära.
- Insert one AAA battery, ensuring the correct polarity (+/-) as marked inside the compartment.
- Pange patareipesa kate tagasi, kuni see kindlalt paika klõpsatab.
2.2 Esmane sisselülitamine
Pärast aku paigaldamist vajutage nuppu 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. Kasutusjuhised
3.1 Põhiarvutused
Enter numbers using the numeric keypad and perform operations using the +, -, ×, ÷ keys. Press = tulemuse saamiseks.
Example: To calculate 15 + 7:
- Vajutage 1 5
- Vajutage +
- Vajutage 7
- Vajutage = (Tulemus: 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 REŽIIM then select DEG if needed).
- Vajutage patt
- Vajutage 3 0
- Vajutage = (Tulemus: 0.5)
3.3 funktsiooniklahvi
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
- Vajutage x² (Tulemus: 25)
Example: To calculate √x (square root of a number):
- Vajutage √
- Enter the number, e.g., 2 5
- Vajutage = (Tulemus: 5)
3.4 Mälufunktsioonid
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+: Lisab kuvatud väärtuse sõltumatule mällu.
- M-CLR: Clears the independent memory.

4. Hooldus
4.1 Puhastamine
Kalkulaatori puhastamiseks kasutage pehmet ja kuiva lappi. Kangekaelse mustuse korral nühkige seda kergelt.ampen the cloth with water and a mild detergent, then wipe dry immediately. Do not use abrasive cleaners, solvents, or spray directly onto the calculator.
4.2 Aku vahetamine
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 Säilitamine

5. Veaotsing
| Probleem | Võimalik põhjus | Lahendus |
|---|---|---|
| Ekraan on tühi või tuhm. | Tühja või tühja patareiga; vale patareide paigaldamine. | Vahetage AAA-patareid, veendudes õiges polaarsuses. |
| Valed arvutustulemused. | 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. |
| Klahvid ei reageeri. | Calculator frozen; physical damage. | Vajutage ON/C. If unresponsive, press the RESET button. If problem persists, contact support. |
| Ekraanil kuvatakse teadet "VIGA". | Mathematical error (e.g., division by zero, invalid function input). | Review your input and the mathematical operation. Press ON/C vea kustutamiseks. |
