If the board does not do so, the defendant may proceed to offer evidence.(b) The board shall have the power to administer oaths or affirmations to witnesses and to adjourn an uncompleted hearing from day to day.(c) A stenographic record or a recording of the hearing shall not be made unless a party does so at his or her own expense.
