(a) If it appears after inquiry and examination that a defendant is not financially able to employ an attorney and is otherwise eligible for the appointment of counsel to represent him the Court shall appoint the office of Public Advocate as his counsel, subject to existing law and the regulations of that agency.

(b) In the event a defendant shall insist upon representing himself without counsel, the defendant shall be brought before the Court and be examined by the Court concerning his understanding of the proceedings and possible consequences to him in the proceedings, his right to the assistance of counsel, and all other relevant matters. If the Court is convinced that defendant is aware of his rights and has waived them knowingly, voluntarily, and intelligently, the Court shall permit him to proceed without counsel and shall by written order relieve any counsel previously appointed.
