2. Konfigurazioa
2.1 Bateriaren instalazioa
The Sharp EL-531TH calculator requires one AAA battery for operation. A battery is typically included with the product.
- Bilatu kalkulagailuaren atzealdean dagoen bateriaren konpartimentuaren estalkia.
- Irristatu estalkia geziak adierazten duen norabidean.
- Insert one AAA battery, ensuring the correct polarity (+/-) as marked inside the compartment.
- Jarri bateriaren konpartimentuaren estalkia ondo sartu arte klik egin arte.
2.2 Hasierako piztea
Bateria instalatu ondoren, sakatu 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. Funtzionamendu-argibideak
3.1 Oinarrizko kalkuluak
Enter numbers using the numeric keypad and perform operations using the +, -, ×, ÷ keys. Press = emaitza lortzeko.
Example: To calculate 15 + 7:
- Sakatu 1 5
- Sakatu +
- Sakatu 7
- Sakatu = (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 MODUA then select DEG if needed).
- Sakatu bekatua
- Sakatu 3 0
- Sakatu = (Result: 0.5)
3.3 Funtzio teklak
Many keys have secondary functions, accessed by pressing the 2nd 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
- Sakatu x² (Result: 25)
Example: To calculate √x (square root of a number):
- Sakatu √
- Enter the number, e.g., 2 5
- Sakatu = (Result: 5)
3.4 Memoria funtzioak
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. Mantentzea
4.1 Garbiketa
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 Bateria ordezkatzea
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 Biltegiratzea
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.
