Safety Precautions
For your correct and safe operations on the equipment, please carefully read and
strictly observe the following safety instructions:
u
High optical power can cause bodily harm, especially to eyes. Never look
directly into the end of the optical transmitter fiber jumper or the end of its active
connector.
u
Exercise care if you must bend fibers. If bends are necessary, the fiber bending
radius should never be less than 38 mm.
u
Overloaded power sockets or damaged cables and connectors may cause
electric shock or fire. Regularly check electrical cables. If any of them is
damaged, replace it immediately.
u
Use the power supply adapter provided in the package only. Using other
adapters may cause equipment damage or operation failures.
u
Install the equipment in a well-ventilated environment without high temperature
or direct sunlight to protect the equipment and its components from overheating,
which may result in damage.
u
Cut off the power supply for the equipment in lightning weather and disconnect
all the wires and cables (such as the power cable, network cable and phone
cable) from the equipment, so as to prevent the equipment from being
damaged by lightning.
u
Do not place the equipment in a wet or damp environment. Water seepage will
lead to abnormal operation of the equipment and short circuit, which may cause
dangers and should be prohibited.
u
Do not lay this equipment on an unsteady base.
