above and around the device for heat dissipation. During the installation, keep the device away from heat or
water sources, and electric appliances that generate strong magnetic or electric fields, such as microwave ovens,
refrigerators, and mobile phones.
The power supply voltage of the device must meet the requirements on the input voltage of the device.
Do not use any power adapters that are not in the standard configuration. Otherwise, the device may
malfunction or be unsafe.
Dry your hands before connecting or disconnecting cables. Stop the device and switch the device off before
connecting or disconnecting cables.
Do not place any object on the device, preventing the device from being damaged due to overheating or
deformation.
Prevent objects, such as metal or water, from entering the device through the heat dissipation hole.
Switch the device off and disconnect all cables, including the power cable, network cable, and phone cable,
during periods of lightning activities.
Do not connect network cables, phone cables, power adapters, or power adapter cables outdoors, preventing
device damage and bodily injuries that are prone to occur during thunderstorms.
If an abnormality occurs, for example, liquid entering the device, smoke, unusual sound, and smell,
immediately stop the device, switch the device off, disconnect all cables (such as the power cable, and network
cable) from the device, and contact the authorized service center.
Do not disassemble the device without permission. In the event of a device fault, contact the authorized
