2. Setha
2.1 Ukufakwa kwebhethri
The Sharp EL-531TH calculator requires one AAA battery for operation. A battery is typically included with the product.
- Thola isembozo segumbi lebhethri ngemuva kwesibali.
- Slayida isembozo siye ohlangothini oluboniswe umcibisholo.
- Insert one AAA battery, ensuring the correct polarity (+/-) as marked inside the compartment.
- Miselela ikhava yengxenye yebhethri ize ichofoze ngokuvikelekile endaweni.
2.2 Amandla Okuqala Avuliwe
Ngemva kokufaka ibhethri, cindezela inkinobho VULA/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. Iziqondiso Zokusebenza
3.1 Izibalo Eziyisisekelo
Enter numbers using the numeric keypad and perform operations using the +, -, ×, ÷ keys. Press = ukuthola umphumela.
Example: To calculate 15 + 7:
- Cindezela 1 5
- Cindezela +
- Cindezela 7
- Cindezela = (Result: 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 IMODE then select DEG if needed).
- Cindezela isono
- Cindezela 3 0
- Cindezela = (Result: 0.5)
3.3 Okhiye Bomsebenzi
Many keys have secondary functions, accessed by pressing the I-F yesibili 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
- Cindezela x² (Result: 25)
Example: To calculate √x (square root of a number):
- Cindezela √
- Enter the number, e.g., 2 5
- Cindezela = (Result: 5)
3.4 Imisebenzi Yememori
The calculator includes memory functions to store and recall values.
- I-STO: Stores the displayed value into a memory variable (A-F, X, Y, M).
- I-RCL: Recalls a value from a memory variable.
- M+: Adds the displayed value to the independent memory.
- M-CLR: Clears the independent memory.

4. Isondlo
4.1 Ukuhlanza
To clean the calculator, use a soft, dry cloth. For stubborn dirt, slightly dampen 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 Ukushintshwa Kwebhethri
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 Isitoreji
Store the calculator in a cool, dry place, away from direct sunlight and extreme temperatures. Use the provided protective cover to prevent scratches and damage to the keys and display.
5. Ukuxazulula izinkinga
| Inkinga | Imbangela Engenzeka | Isixazululo |
|---|---|---|
| Isibonisi asinalutho noma sifiphele. | Ibhethri ephansi noma efile; ukufakwa kwebhethri okungalungile. | Shintsha ibhethri le-AAA, uqinisekise ukuthi i-polarity ilungile. |
| Imiphumela yokubala engalungile. | Incorrect mode setting (e.g., RAD instead of DEG); input error; memory error. | Check the mode setting (DRG key). Review input. Press SETHA KABUSHA button (located on the back, requires a thin object like a paperclip) to clear all memory and settings. |
| Okhiye abaphenduli. | Calculator frozen; physical damage. | Cindezela VULA/C. If unresponsive, press the SETHA KABUSHA 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 VULA/C ukusula iphutha. |
