    Read this manual carefully before operating the laser for the first time. Pay special attention to the Safety chapter. The SR AOM series is designed and sold for use in Original Equipment Manufacturer (OEM) systems and is not to be used as a stand-alone laser. The OEM is responsible for compliance with all applicable safety regulations.
