When the unit is powered on, the USB light flashes. The program select display first says "06" briefly then it says "UP". I've tried connecting it to a computer via USB and it read the device but after restart, everything was the same. I cannot get any other lights to blink, nor can I get the display to show anything other than "06". Can someone please advise if this unit is broken? I've also tried finding out information on a factory reset but was unable to find anything for the MX400, only the MX200 had factory reset instructions. Thanks in advance.
