Instructions for use

- Avoid eye and skin exposure to direct radiation during operation. - ESD precautions must be taken during storage, transportation and operation. - Short-circuit is required between pins during storage and transportation. - Please connect pins to wires by solder instead of using socket when operation current is higher than 6A. - Make sure the fiber output end is properly cleaned before operation of laser. Follow safety protocols to avoid injury when handling and cutting the fiber.
