6 عیب یابی
اگر با دوربین خود با مشکل مواجه شدید، به مراحل عیبیابی رایج زیر مراجعه کنید:
- دوربین روشن نمیشود: مطمئن شوید که باتری کاملاً شارژ شده و به درستی در جای خود قرار گرفته است. از یک باتری شارژ شده دیگر استفاده کنید.
- تصاویر تار هستند: Check that the lens is properly attached and clean. Verify focus settings (autofocus or manual focus) and ensure sufficient shutter speed to prevent motion blur.
- خطای کارت حافظه: Reinsert the memory card. If the issue persists, try a different memory card. Ensure the card is compatible and not full.
- ضبط ویدیو به طور غیرمنتظره متوقف میشود: This may be due to the memory card speed or camera overheating. Use a high-speed memory card (V90 recommended for 4K recording). The camera features a heat-dissipating structure for extended recording, but continuous high-resolution recording in hot environments can still lead to shutdowns.
- مشکلات اتصال: Ensure Wi-Fi and Bluetooth are enabled on both the camera and your mobile device. Refer to the Imaging Edge Mobile application for specific connection instructions.
