• Interval: Time interval between the two synchronizing actions with NTP server. The unit is minute.

5. Click the Apply button to save and exit the interface.
The time synchronization interval can be set from 1 to 10080min, and the default value is 60min. If the
device is connected to a public network, you should use a NTP server that has a time synchronization function,
such as the server at the National Time Center (IP Address: 210.72.145.44). If the device is setup in a more
customized network, NTP software can be used to establish a NTP server used for time synchronization.
9.2.4 Configuring UPnP™
Purpose:
UPnP™ can permits the device seamlessly discover the presence of other network devices on the network and
establish functional network services for data sharing, communications, etc. If you want to use the UPnP™
function to enable the fast connection of the device to the WAN via a router, you should configure the UPnP™
parameters of the device.
Before you start:
If you want to enable the UPnP™ function of the device, you must enable the UPnP™ function of the router
to which your device is connected. When the network working mode of the device is set as multi-address, the
Default Route of the device should be in the same network segment as that of the LAN IP address of the
router.
Steps:
1. Enter the Network Settings interface.
Menu > Configuration > Network
2. Select the UPnP tab to enter the UPnP™ interface.
