2. Setup
2.1 Installazzjoni tal-batterija
The Sharp EL-531TH calculator requires one AAA battery for operation. A battery is typically included with the product.
- Sib l-għatu tal-kompartiment tal-batterija fuq wara tal-kalkulatur.
- Żerżaq l-għatu 'l barra fid-direzzjoni indikata mill-vleġġa.
- Insert one AAA battery, ensuring the correct polarity (+/-) as marked inside the compartment.
- Erġa’ poġġi l-għatu tal-kompartiment tal-batterija sakemm tikklikkja sew f’postu.
2.2 Qawwa Inizjali
Wara li tinstalla l-batterija, agħfas il- ON/Ċ 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. Istruzzjonijiet Operattivi
3.1 Kalkoli Bażiċi
Enter numbers using the numeric keypad and perform operations using the +, -, ×, ÷ keys. Press = biex tikseb ir-riżultat.
Example: To calculate 15 + 7:
- Agħfas 1 5
- Agħfas +
- Agħfas 7
- Agħfas = (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 MODALITÀ then select DEG if needed).
- Agħfas dnub
- Agħfas 3 0
- Agħfas = (Result: 0.5)
3.3 Ċwievet tal-Funzjoni
Many keys have secondary functions, accessed by pressing the It-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
- Agħfas x² (Result: 25)
Example: To calculate √x (square root of a number):
- Agħfas √
- Enter the number, e.g., 2 5
- Agħfas = (Result: 5)
3.4 Funzjonijiet tal-Memorja
Il-kalkulatur jinkludi funzjonijiet tal-memorja biex jaħżen u jfakkar il-valuri.
- 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. Manutenzjoni
4.1 Tindif
Biex tnaddaf il-kalkulatur, uża drapp artab u niexef. Għal ħmieġ iebes, nixxef ftit.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 Sostituzzjoni tal-batterija
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 Ħażna
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 Issolvi l-problemi
| Problema | Kawża Possibbli | Soluzzjoni |
|---|---|---|
| Id-displej huwa vojt jew mudlam. | Batterija baxxa jew mejta; installazzjoni ħażina tal-batterija. | Ibdel il-batterija AAA, waqt li tiżgura l-polarità korretta. |
| Riżultati tal-kalkolu mhux korretti. | 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. |
| Iċ-ċwievet ma jirrispondux. | Calculator frozen; physical damage. | Agħfas ON/Ċ. 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/Ċ biex tnaddaf l-iżball. |
