    Attention

    Insure the package is not defaced. If you think the equipment has been damaged, please don't electrify to avoid worse damage or do harm to the operator.

    ● Before the equipment is power on, make sure the housing and the power socket is reliably grounded. The grounding resistance should be <4Ω, so as to effectively protect against surges and static electricity.

    ● Optical transmitter is professional equipment. Its installation and debugging must be operated by special technician. Read this manual carefully before operating to avoid damage to equipment caused by fault operation or accident harm to the operator.

    ● While the optical transmitter is working or debugged, there is an invisible laser beam from the optical output adapter on the front panel. Avoiding permanent harm to the body and eye, the optical output should not aim at the human body and people should not look directly at the optical output with the naked eye!

    ● When the fiber connector is not in use, it should be put on the dust jacket to avoid dust pollution and keep the fiber tip clean.
