the Save Settings page), the System Restart page will include a message: “You have changes that need to be
saved. Click here to go to update page.”
Figure 37: System Restart Page if the time was synchronized when there were unsaved changes
To save unsaved changes after the time was synchronized:
1. Click the message. The Save Settings page opens.
2. In the Save Settings page, click Save Changes to System, and then, in the System Restart page, click
Restart System.
In addition, if the unit clock was set ahead more than about 15 minutes during synchronization, instead of the
System Restart page, a message indicating that your configuration session has expired may appear. This does not
mean that the time was not reset correctly. However, you should still restart the unit to fully implement the update,
as follows:
To fully implement the time synchronization when the session expired during the process:
1. Log into the configuration utility again.
2. Navigate to the System Restart page and click Restart System.
Note: If you made changes to other configuration settings before you updated the time, and did not yet save
them on the unit (i.e., you clicked Update in one or more of the screens, but did not yet save the changes in
the Save Settings page), navigate to the Save Settings page, click Save Changes to System, and then, in
the System Restart page, click Restart System.
Configuring Automatic Time Setting
The Video Gateway can automatically keep its clock up to date by connecting to an NTP time server at specified
intervals. If you are configuring an MVG or a CVG-M, you can choose to use a land-based time server (on the
internet or on a local network) or GPS-based time synchronization for this purpose.
NOTE: If the Video Gateway unit is not connected to the internet most or all of the time, does not have GPS
support, and cannot connect to an alternative local time server, this feature will not keep the unit time
accurate.
