Safety Precautions
To use the device properly and safely, read the safety precautions carefully before using the device
and strictly observe these precautions when using the device.
Store devices and accessories in temperature –10°C to +35°C and relative humidity 30%–85%
RH for at most 9 months. If the ambient temperature or relative humidity is overhigh or overlow,
the device may be faulty.
Used only indoors. Do not lead metallic cables, such as network cables and telephone lines
outdoors.
Do not look directly into the optical port without eye protection.
Keep the device out of the reach of children as the components or accessories may be
swallowed.
Install the device in strict compliance with the requirements of the supplier. Reserve a space of
at least 10 cm above and around the device for heat dissipation. During the installation, keep
the device away from electric appliances that generate strong magnetic or electric fields, such
as microwave ovens, refrigerators, and mobile phones.
The described input voltage range should comply with the local power grid. For example, the
input voltage of the adapter is 200–240 V AC for European Union; the input voltage of the
adapter is 100–140 V AC for America.
If the power adapter is damaged and its internal circuit is exposed due to manmade factors, do
not touch the exposed circuit, which may bring safety risks.
Only power adapters delivered with the device can be used. Otherwise, the device may be
abnormal or unsecure.
Dry your hands before connecting or disconnecting cables. Stop the device and switch off the
power before connecting or disconnecting cables.
Do not place any object on the device, so that the device will not be damaged due to
overheating or deformation.
Prevent objects, such as metal, from entering the device through the heat dissipation hole.
Switch off the power and disconnect all cables, including the power cable, optical fiber, and
network cable, during periods of lightning activities. The socket-outlet shall be installed near
the power adapter and shall be easily accessible. Before use the power adapter, please check
no damage on the adapter.
Do not lead the strength member of the optical fiber or other metal parts indoors. Do not install
telephone lines, network cables, power adapters or power adapter cables outdoors. Adopting
these measures will help prevent device damage and bodily injuries which are especially prone
during thunderstorms.
If an abnormality occurs, for example, liquid entering the device, smoke, unusual sound,
and smell, stop the device immediately, switch off the power, disconnect all cables (such as
the power cable, optical cable, and network cable) to the device, and contact the authorized
service center.
Do not disassemble the device without permission. In the case of a device fault, contact the
authorized service center.
Dispose of the packing materials, expired batteries, and old or abandoned devices in
accordance to local laws and regulations (recycling them is strongly recommended).
Do not change the structure, safety design, or performance design of the device without prior
authorization.
The device should be installed and operated with a minimum distance of 20 cm between the
radiator and your body.
