I've been on this forum for about a week now reading up and learning way more about radar detectors than I ever thought there was to know. As I'm reading I am having some trouble with the abbreviations. I know RD=radar detoctor and I think LEO=law enforcement officer. Those are the only two that I can figure out. Could ya'll please feel me in on the meaning of the other abbreviated words like I/O and the others. I can't remember them all right now, but do recall coming across several that I had no clue of the meaning. I'm sure once I figure them out they will make perfect since. Thanks.
