View system notifications (legacy)
When you select DVR on the main menu, if you see next to the Manage option, it indicates that you have one or more system notifications. To review your system notifications, select Manage. The DVR manage screen appears.
If there are any notifications, a number other than 0 appears in the System Notifications box. Select System Notifications to read the messages.
The Notifications screen lists all of your system messages. Navigate to any message on the list and press ok to display it. After you read the message, select Delete and press ok to remove that message from the list.
If you want to delete all of the messages at once, on the Notification screen, select Delete All Messages. This action removes the messages from your storage device.
