SDS100/SDS200: SUM Help!!!

[Metrofire31]

I recently purchased an SDS200 scanner and when I attempted to register it on MYUNIDEN.COM, I kept getting error messages related to my choice of the SUM digits. The scanner ESN is 3842xxxx002927-0E0. (All the 0's are zeros). I tried 0E0, I tried 927 and got an error message for both. Can someone help me determine the correct SUM digits?

Just enter the last nine digits and that should work.

0E0 is the checksum (for the record)
That is zero-E-zero.
