The 602 code was a "bogus" code that the earlier Smarty tunes produced, did not hurt anything, was just an annoyance. You must have an older Smarty, or running older software, because Marco corrected that issue in the newer tunes.

This info is only correct if you have a 3rd gen, fill out your signature in the User CP, it's easier to give you accurate info.
