Pay attention to the power load of the outlet or prolonged lines. An
overburden power outlet or damaged lines and plugs may cause electric
shock or fire accident. Check the power cords regularly. If you find any
damage, replace it at once.
Proper space left for heat dissipation is necessary to avoid any damage
caused by overheating to the device. The holes on the device are designed
for heat dissipation to ensure that the device works normally. Do not cover
these heat dissipation holes.

4 PC Network Configuration and Login
4.1 PC Network Configuration
Each network interface on the PC should either be configured with a statically defined
IP address and DNS address, or be instructed to automatically obtain an IP address
using the network DHCP server. MG7540 provides a DHCP server on its LAN and it
is recommended to configure your LAN to automatically obtain its IP address and
DNS server IP address.
The configuration principle is identical but should be carried out differently on each
operating system.
The following displays the TCP/IP Properties dialog box on Windows 7.
