    Precautions:

    This product emits laser radiation during operation. Never allow the laser beam to strike any part of the human body.

    This product is an electrostatic-sensitive device. Please operate it in an ESD-protected area and ensure that tools in direct contact with the device are properly grounded. Improper operation and use may cause permanent and irreversible damage to the product.
    This product is equipped with optical connectors. After testing and inspection, please promptly attach the dust caps to avoid prolonged exposure of the optical connectors, which may lead to contamination or damage to the end faces.
