2. Sozlash
2.1 Batareyani o'rnatish
The Sharp EL-531TH calculator requires one AAA battery for operation. A battery is typically included with the product.
- Kalkulyatorning orqa tomonidagi batareya bo'limi qopqog'ini toping.
- Qopqoqni strelka bilan ko'rsatilgan yo'nalishda suring.
- Insert one AAA battery, ensuring the correct polarity (+/-) as marked inside the compartment.
- Batareya bo'linmasi qopqog'ini joyiga mahkam o'rnashguncha qayta joyiga qo'ying.
2.2 Dastlabki yoqish
Batareyani o'rnatgandan so'ng, tugmasini bosing 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. Foydalanish bo'yicha ko'rsatmalar
3.1 Asosiy hisob-kitoblar
Enter numbers using the numeric keypad and perform operations using the +, -, ×, ÷ keys. Press = natijaga erishish uchun.
Example: To calculate 15 + 7:
- bosing 1 5
- bosing +
- bosing 7
- bosing = (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 REJIM then select DEG if needed).
- bosing gunoh
- bosing 3 0
- bosing = (Result: 0.5)
3.3 funktsiya tugmachalari
Many keys have secondary functions, accessed by pressing the 2-chi 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
- bosing x² (Result: 25)
Example: To calculate √x (square root of a number):
- bosing √
- Enter the number, e.g., 2 5
- bosing = (Result: 5)
3.4 Xotira funktsiyalari
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. Xizmat ko'rsatish
4.1 Tozalash
To clean the calculator, use a soft, dry cloth. For stubborn dirt, slightly dampMatoni suv va yumshoq yuvish vositasi bilan arting, so'ngra darhol quriting. Abraziv tozalagichlar, erituvchilardan foydalanmang yoki to'g'ridan-to'g'ri kalkulyatorga purkamang.
4.2 Batareyani almashtirish
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 Saqlash
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. Muammolarni bartaraf qilish; nosozliklarni TUZATISH
