If at any time a member of the fund undergoes a change of employment to a position that does not qualify the member as a "peace officer" as such term is defined in this chapter, or if his or her job description changes in a manner that is inconsistent with such definition, such member shall have an affirmative duty to notify the board of such change immediately. The board is not authorized to accept membership dues from any such member or to pay benefits calculated on service after such a change of employment or job description.
