2. الإعداد

2.1 تركيب البطارية

The calculator comes with one LR44 battery pre-installed, which serves as a backup power source. The primary power source is solar. If the display becomes dim or unresponsive in sufficient light, the battery may need replacement.

1. تأكد من إيقاف تشغيل الآلة الحاسبة.
2. حدد مكان غطاء حجرة البطارية على الجزء الخلفي من الآلة الحاسبة.
3. Using a small screwdriver, carefully remove the screw(s) securing the cover.
4. Remove the cover and replace the old LR44 battery with a new one, ensuring correct polarity (+/-).
5. أعد تركيب غطاء حجرة البطارية وثبته بالبرغي (البراغي).

2.2 التشغيل الأولي

لتشغيل الآلة الحاسبة، اضغط على [على] button. The calculator will display '0' on the screen. If the display is blank, ensure there is sufficient light for the solar panel or check the battery installation.

3. تعليمات التشغيل

This section provides a guide to the various functions and operations of your Casio fx-300MS Plus 2nd Edition Scientific Calculator.

3.1 العمليات الحسابية الأساسية

Enter numbers using the numeric keypad and perform operations using the [+], [-], [×]، و [÷] أزرار. صحافة [=] لعرض النتيجة.

3.2 الوظائف العلمية

The calculator offers a wide array of scientific functions. Many functions are accessed by pressing the [تحول] key followed by the desired function key (indicated in yellow above the keys).

• الدوال المثلثية: يستخدم [خطيئة], [cos], [تان] للجيب، وجيب التمام، والظل. الدوال العكسية (sin⁻¹, cos⁻¹, tan⁻¹يتم الوصول إليها عبر [تحول].
• Logarithms: يستخدم [سجل] for base-10 logarithm and [ln] for natural logarithm.
• القوى والجذور: يستخدم [x²] for square, [√] for square root, [x³] for cube, and [³√] for cube root. General powers ([^]) and roots ([SHIFT] [^]) are also available.
• Factorials: يستخدم [x!] (تم الوصول إليه عبر [تحول]) for factorial calculations.

3.3 Fraction Calculations

The dedicated fraction key [a b/c] allows for easy entry and calculation of fractions and mixed numbers. Use [SHIFT] [a b/c] to convert between improper fractions, mixed numbers, and decimal equivalents.

3.4 Statistical Calculations

To enter Statistics Mode, press [وضع] and select the appropriate statistical option (e.g., SD for standard deviation, REG for regression). Follow the on-screen prompts to input data and perform calculations.

3.5 Variable Memory

The calculator can store up to 9 variables (A-F, X, Y, M). To store a value, enter the number, press [ستو], and then press the alpha key corresponding to the desired variable (e.g., [ALPHA] [A]). To recall a value, press [RCL] and the variable key.

3.6 الأوضاع والإعدادات

اضغط على [وضع] button to cycle through different calculation modes (e.g., COMP for basic arithmetic, STAT for statistics). The [يثبت] button (accessed via [SHIFT] [MODE]) allows you to configure display settings, angle units (degrees, radians, grads), and number formats.

3.7 إيقاف التشغيل

لإيقاف تشغيل الآلة الحاسبة، اضغط على [تحول] متبوع ب [AC] (إيقاف).

4. الصيانة

4.1 التنظيف

To clean the calculator, use a soft, dry cloth. For stubborn dirt, lightly dampen the cloth with water and a mild detergent, then wipe dry. Avoid using strong solvents or abrasive cleaners, as these can damage the calculator's surface or display.

4.2 التخزين

When not in use, store the calculator in its protective hard case to prevent scratches and damage. Keep it away from extreme temperatures, humidity, and direct sunlight. The solar panel requires light to function, but prolonged exposure to intense heat can be detrimental.

4.3 استبدال البطارية

If the display becomes dim or calculations are slow, even in good lighting, it may be time to replace the LR44 backup battery. Refer to section 2.1 for battery installation instructions.

5. استكشاف الأخطاء وإصلاحها

• العرض فارغ: Ensure the calculator is in sufficient light for the solar panel. If it remains blank, replace the LR44 backup battery.
• نتائج غير صحيحة: Check the current mode (e.g., degrees vs. radians for trigonometric functions). Press [SHIFT] [MODE] to access setup and adjust settings. Ensure correct input of numbers and operations.
• تتجمد الآلة الحاسبة: اضغط على [AC] button to clear the current calculation. If the issue persists, try removing and reinserting the battery to perform a hard reset.
• الأزرار لا تستجيب: Ensure no debris is lodged under the keys. Clean the calculator as described in section 4.1.
