If the defendant appears at the arraignment without counsel, the court must inform the defendant of his right to counsel, must accord the defendant opportunity to exercise that right, and must take any action necessary to effectuate the right. If the defendant does not file a written request for arraignment, the court, in addition to entering a plea of not guilty on behalf of the defendant, shall also verify that the defendant is aware of the right to counsel, that the defendant has been given the opportunity to exercise that right, and must take any action necessary to effectuate that right on behalf of the defendant.
