Why doesn't the DVR detect my USB export device for exporting recorded files
There's a chance that the DVR and your USB device is not compatible. Please refer to
our company's website to view a list of compatible devices.
My DVR is in Live View mode and the menu does not show up. It does not respond to
the mouse, the front panel, the remote or keyboard
Your DVR may be in auxiliary mode. This occurs when the F1 is pressed on the front
panel. To return to the previous mode of operation, press the F1 again.
