2. الإعداد
2.1 مصدر الطاقة
The Casio fx-115MS PLUS SR calculator operates using both solar power and a battery. This dual power system ensures reliable operation in various lighting conditions. Under sufficient light, the calculator will primarily use solar power. In low light conditions or when performing complex calculations, the battery will provide power.
2.2 الاستخدام الأولي
- Remove the calculator from its packaging.
- Slide off the protective hard case.
- اضغط على ON button to power on the calculator. If the display does not appear, ensure there is adequate light for solar power or check the battery.
- Adjust display contrast if necessary using the appropriate function (refer to the 'Operating Instructions' section for details on display settings).
3. تعليمات التشغيل

4. الصيانة
4.1 التنظيف
لتنظيف الآلة الحاسبة، امسح السطح برفق بقطعة قماش ناعمة وجافة. لإزالة الأوساخ المستعصية، افركها قليلاً.ampen the cloth with water and then wipe dry. Avoid using harsh chemicals, abrasive cleaners, or solvents, as these can damage the calculator's casing وعرضها.
4.2 التخزين
When not in use, store the calculator in its slide-on hard case to protect it from dust, scratches, and impacts. Avoid exposing the calculator to extreme temperatures, high humidity, or direct sunlight for extended periods.
4.3 استبدال البطارية
While the calculator utilizes solar power, it also contains a backup battery. If the display becomes dim or erratic in adequate lighting, the battery may need replacement. Refer to the manufacturer's guidelines for specific battery type and replacement procedures. Improper battery replacement can void the warranty.
5. استكشاف الأخطاء وإصلاحها
This section addresses common issues you might encounter with your Casio fx-115MS PLUS SR Scientific Calculator.
5.1 Calculator Does Not Turn On or Display is Blank
- التحقق من الإضاءة: Ensure the solar panel is exposed to sufficient light.
- بطارية: If operating in low light or if the display remains blank, the battery may be depleted. Consider replacing the battery according to manufacturer instructions.
- إعادة تعيين: A small reset button (often on the back) may be present. Use a thin, pointed object to press it. Note that this will clear all memory.
5.2 الإيقاف التلقائي
The calculator is designed to automatically shut off after a period of inactivity (approximately 6 minutes) to conserve power. This is a normal function. To resume operation, press the ON button. Be aware that calculations in progress may be lost upon automatic shut-off.
5.3 Wobbly Case
The slide-on hard case is designed for protection during transport. If the calculator feels wobbly when placed on a surface with the case underneath, it is due to the rounded design of the case. For stable operation, remove the case and place the calculator directly on a flat surface.
5.4 Incorrect Calculation Results
- Input Error: Carefully re-enter the calculation to ensure accuracy. Utilize the two-line display to verify your input.
- إعدادات الوضع: Check if the calculator is in the correct mode (e.g., DEG, RAD, GRD for angles; COMP for complex numbers).
- مسح الذاكرة: Clear all memory and variables if unexpected results persist.
