To access Reset - Units, press [SPECIAL], <9reset>, <2units>

The only thing I saw in the troubleshooting checklist in the manual that closely resembles the error you listed was for <Fatal Error> or <Fatal Fault>: Encountered unresolved internal software conflict.  Says the solution is to Cycle power to clear.
