Auxiliary Codes
RIR1-SSB T-5 June 2008
U-5 January 2009
Auxiliary Code Breakdown
The auxiliary code is the rst two characters in the serial number. The rst character
indicates the year. Years progress or regress in alphabetical order. The series runs from
"A" through "V" and the letters "I" and "O" are skipped. The second character indicates
signicant part changes within a year. Base is "5" and this number advances for each
change.
Note About Ordering Parts
Most assemblies cannot be ordered as complete units; parts in the assemblies generally
must be ordered separately.
