Sub-element 10 (designated as "zero" [0] in the question pool numbering scheme) is a new topic added in 1998 as a result of the FCC's updated RF safety standards. Currently there were only 9 topic areas in the Element 4 question pool that expired 6/30/08. Subsequent Element 4 question pools have 10 subtopic areas.
