Hi all,

We seem to be having an issue with a NCU 730.3. It is throwing an error code of 8 on the 7 segment display. We have tried changing the fan/battery box but this still dosn't help. Have restarted the machine countless times but still no effect. Can I get some feedback on what ellse to check?
