Safety Information
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.

Safety precautions:

 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.
