I would suggest that you reset the serial numbr in the firmware.  go to:

  • Options
  • Diagnostics
  • Instrument Status

As I recall you need to have the cursor on the serial number line, and then depress the "." (decimal) key.  You should then be able to enter the numerical portion of the serial number.  I believe if you press the "Mode/Type" button you can change the alpghabetic country code.
