V. Usage Precautions

  1. Prevent Electrostatic Discharge (ESD) when handling LED panels:
    • Wear grounded anti-static wrist straps or anti-static gloves.
    • Ensure proper grounding of the screen; ground resistance must be ≤ 10 ohms. Conduct inspections every 6 months.
  2. Cleaning the LED panel surface:
    Do not use unknown chemical liquids. Clean gently using a clean, lint-free cloth or a soft cloth dampened with purified water.
  3. Electrical safety:
    The power distribution box must be equipped with surge protectors and other protective devices.
