Before you can use your LNR200 / LNR300 Series NVR to back up video to an external USB device, such as USB flash drive or self-powered external USB hard disk drive (HDD) (not included), you must format the drive.
IMPORTANT: Formatting the external USB device will erase all data on the drive.
The following instructions require you to access your system using your NVR and a monitor.
To format the USB external device:
Insert an external USB device into one of the USB ports on the NVR.
Right-click on the Live View, and then click Menu.
Click Export and then click Normal.
Click Quick Export.
Click OK to confirm and wait for formatting to complete.
Once you have completed formatting the external USB device, you can use it to back up video.
