A couple of things:
– For a factory reset, please make sure the unit is unplugged, then hold the pushbutton in as you plug it back in, then keep holding the button for about 12 seconds. It is also possible to reset the unit with our utility by activating the “restore to factory configuration” button.
We would like to see this lockup mode as we have never experienced it. If the problem persists, please call our support line to arrange an exchange.
