5.OPERATING NOTES:
     1.Avoid eye exposure to direct or scattered radiation.
     2.ESD precautions must be taken.
     3.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 root of the pins. Soldering temperature should be lower than 260 and time shorter than 10 seconds.
     4.Use constant current power supply. Avoid surge current.
     5.Laser diode must be used according to the specifications.
     6.A minimum bend radius should be 300 times greater than the fiber cladding diameter.
     7.Laser diode must work with good cooling.
     8.Operation temperature is 10~30.
     9.Storage: -20~ +70, all pins short-circuit.
