2. سيٽ اپ ۽ شروعاتي استعمال

2.1 طاقت جو ذريعو

The EL-531TG-GY calculator operates using both solar power and a single LR44 button cell battery. The solar panel provides power in well-lit environments, while the battery ensures operation in low-light conditions or when solar power is insufficient. An LR44 battery is included with the calculator.

2.2 آن/بند ڪرڻ

• To turn the calculator ON، دٻايو آن/سي چاٻي
• To turn the calculator بند، دٻايو ٻيو ايف چاٻي پٺيان بند key (which is typically the same as آن/سي).

2.3 Initial Display Settings

Upon first use or after a reset, the calculator will typically default to certain settings (e.g., DEG for angle units). Refer to Section 3.3 for details on changing mode settings.

3. آپريٽنگ هدايتون

3.1 بنيادي رياضي آپريشن

Enter numbers using the numeric keypad. Use the +, -, ×، ۽ ÷ keys for addition, subtraction, multiplication, and division, respectively. Press = to obtain the result.

3.2 Scientific Functions

The calculator performs over 273 advanced scientific functions. Many functions are accessed by pressing the ٻيو ايف key before the desired function key.

• ٽرگنوميٽرڪ ڪم: استعمال ڪريو گناهه, cos, رنگ. Inverse functions (sin⁻¹, cos⁻¹, tan⁻¹) are accessed via ٻيو ايف.
• Logarithmic Functions: استعمال ڪريو لاگ (base 10) and ln (natural logarithm).
• Powers and Roots: استعمال ڪريو x², √, x³, ³√.
• جزا: استعمال ڪريو d/c key for fraction input and conversion.

3.3 Mode Settings (DEG/RAD/GRAD)

To change the angle unit mode (Degrees, Radians, Gradians):

1. کي دٻايو ڊي آر جي چاٻي
2. بار بار دٻايو ڊي آر جي to cycle through DEG (Degrees), RAD (Radians), and GRAD (Gradians). The current mode is indicated on the display.

3.4 ياداشت جا ڪم

The calculator includes memory functions for storing and recalling values.

• STO (Store): دٻايو ايس ٽي او followed by a variable key (e.g., A, B) to store the displayed value.
• RCL (Recall): دٻايو آر سي ايل followed by the variable key to recall the stored value.
• M+ (ميموري پلس): Adds the displayed value to the independent memory.
• M- (ميموري مائنس): Subtracts the displayed value from the independent memory.

3.5 Multi-Line Playback

The 2-line display allows for Multi-Line Playback, enabling users to review previous calculations and expressions. Use the directional arrow keys (up/down) to scroll through past entries and results. This feature is useful for checking work or re-using parts of previous calculations.

4. سار سنڀال

4.1 صفائي

To clean the calculator, wipe the surface gently with a soft, dry cloth. Do not use abrasive cleaners, solvents, or excessive moisture, as these can damage the display or internal components.

4.2 بيٽري مٽائڻ

The calculator uses one LR44 button cell battery. If the display becomes dim or erratic in low-light conditions, the battery may need replacement. To replace the battery:

1. پڪ ڪريو ته ڪيلڪيوليٽر بند آهي.
2. ڪيلڪيوليٽر جي پوئين پاسي بيٽري جي خاني کي ڳوليو.
3. ڪمري جو ڍڪ احتياط سان کوليو.
4. پراڻي LR44 بيٽري کي هٽايو ۽ هڪ نئين بيٽري داخل ڪريو، صحيح پولارٽي کي يقيني بڻائي (+/-).
5. بيٽري جي ڪمري واري ڍڪ کي محفوظ طور تي بند ڪريو.

4.3 اسٽوريج

When not in use, store the calculator in a cool, dry place away from direct sunlight and extreme temperatures. The hard cover included with the calculator provides protection from scratches and minor impacts.

5. مسئلا حل ڪرڻ

5.1 ڊسپلي مسئلا

• خالي يا مدھم ڊسپلي: Ensure sufficient light for the solar panel. If the issue persists, replace the LR44 battery.
• Erratic Display: This may indicate a low battery. Replace the LR44 battery.

5.2 غلط نتيجا

• Check Mode Settings: Verify that the angle unit (DEG, RAD, GRAD) is set correctly for trigonometric calculations.
• داخل ڪرڻ ۾ غلطي: Review your input using the Multi-Line Playback feature to ensure the expression was entered correctly.
• Memory Contents: If using memory functions, ensure the stored values are correct.

5.3 ڪيلڪيوليٽر جواب نه ڏئي رهيو آهي

If the calculator becomes unresponsive, try performing a reset. Locate the ري سيٽ ڪريو button (often a small recessed button requiring a thin object like a paperclip to press). Pressing this button will clear all memory and return the calculator to its factory default settings.
