Click the bottom-left corner of the screen and then click Setup. Enter your password.
Now click System, then Maintenance, then Upgrade. Click Select File.
If the USB stick does not appear, swap the USB stick and USB mouse around.

Wait for the success message – the unit should restart after a minute or so. If it does not, power-off the NVR Base unit by pressing Shutdown from the bottom-left corner menu.
