Getting Sideboard missmatch on my 5973

Getting Sideboard missmatch on my 5973 after changing the side board.  The error comes up in chemstation but appears to be a warning?  What should I do

Side board mismatch means that there is mismatch between the sideboard (the circuit board the is on the sideplate to which the analyzer) and log amp circuit board.  Newer versions of the log amp can not be used with the older side board.  So you must upgrade both to get rid of the error message.
