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. 

- Soldering point should be close to the middle of the pins. Soldering temperature should be lower than 260℃ and time shorter than 10 second.

- 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.
- Use constant current power supply to avoid surge current during operation. 
- Laser diode must be used according to the specifications.
- Laser diode must work with good cooling.
- Operation temperature ranges from 15℃ to 35℃ .
- Storage temperature ranges from -20℃ to +70℃.
