3.2 ابتدايي استعمال
- پاور آن: فشار ورکړئ AC/آن د کیلکولیټر د چالانولو لپاره تڼۍ.
- د ښودلو چک: Ensure the display shows "0" or a clear reading. If the display is dim, expose the calculator to brighter light or consider battery replacement if issues persist.
4. عملیاتي لارښوونې
۳.۱ اساسي محاسبې
Perform standard arithmetic operations:
- اضافه: Enter first number + second number =
- تخفیف: Enter first number - second number =
- ضرب: Enter first number × second number =
- څانګه: Enter first number ÷ second number =
4.2 سلنهtage محاسبه
د فیصدي محاسبه کولو لپارهtages:
- ExampLe: To find 15% of 200: Enter 200 × 15 %. پایله به ۲۲ وي.
- ExampLe: To add 15% to 200: Enter 200 + 15 %. پایله به ۲۲ وي.

Image 4.1: Close-up of the percentage (%), TAX-, and TAX+ buttons. These keys are used for quick financial calculations.
4.3 Tax Calculations
The calculator features dedicated keys for tax calculations. First, set the tax rate:
- مطبوعاتي د نرخ ټاکل.
- Enter the tax rate (e.g., 5 for 5%).
- مطبوعاتي د نرخ ټاکل بیا خوندي کول.
Once the tax rate is set:
- Add Tax: مقدار داخل کړئ TAX+.
- Subtract Tax: مقدار داخل کړئ مالیه-.
۳.۴ د حافظې دندې
Use memory keys to store and recall values:
- M+: ښودل شوی ارزښت حافظې ته اضافه کوي.
- م-: ښودل شوی ارزښت له حافظې څخه کموي.
- ښاغلی: Recalls the value stored in memory.
- MC: حافظه پاکوي.
4.5 Square Root Calculation
To calculate the square root of a number:
- شمیره دننه کړئ.
- فشار ورکړئ √ (square root) button.

Image 4.2: Close-up of the square root (√) button. This button is used for calculating the square root of a displayed number.
4.6 Time Calculations (H/M/S)
د H/M/S button allows for calculations involving hours, minutes, and seconds. This function treats numbers as sexagesimal (base 60) values for time-related arithmetic.
- Enter the hours, then press H/M/S.
- Enter the minutes, then press H/M/S.
- Enter the seconds, then press H/M/S.
- Perform desired operation (+, -, etc.) and press =.

5. ساتنه
5.1 پاکول
- کیلکولیټر په نرم او وچ ټوکر سره پاک کړئ.
- د کثافاتو پاکوونکي، محلولونه، یا الکول مه کاروئ، ځکه چې دا کولی شي c ته زیان ورسويasing او ښودنه.
5.2 ذخیره کول
- کیلکولیټر په یو سړه او وچ ځای کې وساتئ چې د مستقیم لمر وړانګو او سختې تودوخې څخه لرې وي.
- Avoid placing heavy objects on the calculator to prevent damage to the display or keys.
5.3 د بیټرۍ بدلول
When the display becomes dim or calculations are erratic even in bright light, the battery may need replacement. Refer to the battery compartment on the back of the unit for specific battery type and replacement instructions. Ensure proper polarity when inserting a new battery.
6. ستونزه حل کول
| ستونزه | احتمالي لامل | د حل لاره |
|---|---|---|
| ښودنه خالي یا تیاره ده. | د سولر پینل لپاره کافي رڼا نه ده، یا د بیټرۍ ټیټه کچه. | Move to a brighter area. If problem persists, replace the battery. |
| د ناسمې محاسبې پایلې. | Incorrect input, or memory not cleared. | Double-check input. Press AC to clear all and MC to clear memory before starting a new calculation. |
| کیليګانې بې ځوابه دي. | Dust or debris under keys, or internal malfunction. | Gently clean around keys. If problem persists, contact customer support. |
