مصدر الطاقة

The Staples ST290-CCVS calculator operates on a dual power system: solar and battery. This ensures reliable operation in various lighting conditions.

الطاقة الشمسية: The calculator is equipped with a solar panel located above the display. For optimal performance, ensure the solar panel is exposed to sufficient light. This is the primary power source in well-lit environments.
طاقة البطارية: An internal battery provides power when light is insufficient or absent. The calculator automatically switches to battery power as needed. No user intervention is required for power source selection.

الاستخدام الأولي

Upon first use, or after prolonged storage, simply expose the calculator to light or press the ON/C CE button to activate the display. The calculator is ready for immediate use.

Proper care and maintenance will extend the life of your calculator.

تنظيف: Use a soft, dry cloth to clean the calculator's surface. For stubborn dirt, slightly dampen the cloth with water or a mild, non-abrasive cleaner. Avoid using harsh chemicals, solvents, or abrasive materials, as these can damage the display or casing.
