Attentions
1.Avoid eyes or skin exposure to direct or scattered radiation in case of laser working
2.Anti-static measures must be taken when transporting, storing and using
3.Use constant current power supply to avoid surge when working
4.Used under rated current and rated power, otherwise reduce lifetime
5.Maintain good thermal dissipation during laser operation
