(a) Nature of Arraignment. The arraignment must be conducted in open court or by audio-video communication technology in the discretion of the court and must consist of the judge or clerk or prosecuting attorney reading the indictment or information on which the defendant will be tried to the defendant or stating orally to the defendant the substance of the charge or charges and calling on the defendant to plead thereto. The reading or statement as to the charge or charges may be waived by the defendant. If the defendant is represented by counsel, counsel may file a written plea of not guilty at or before arraignment and thereupon arraignment must be deemed waived.
(b) Effect of Failure to Arraign or Irregularity of Arraignment. Neither a failure to arraign nor an irregularity in the arraignment shall affect the validity of any proceeding in the cause if the defendant pleads to the indictment or information on which the defendant is to be tried or proceeds to trial without objection to such failure or irregularity.
(c) Plea of Guilty after Indictment or Information Filed. If a person who has been indicted or informed against for an offense, but who has not been arraigned, desires to plead guilty thereto, the person may so inform the court having jurisdiction of the offense, and the court shall, as soon as convenient, arraign the defendant and permit the defendant to plead guilty to the indictment or information.
(d) Time to Prepare for Trial. After a plea of not guilty the defendant is entitled to a reasonable time in which to prepare for trial.
(e) Defendant Not Represented by Counsel. Prior to arraignment of any person charged with the commission of a crime, if he or she is not represented by counsel, the court shall advise the person of the right to counsel and, if he or she is financially unable to obtain counsel, of the right to be assigned court-appointed counsel to represent him or her at the arraignment and at all subsequent proceedings. The person shall execute an affidavit that he or she is unable financially or otherwise to obtain counsel, and if the court shall determine the reason to be true, the court shall appoint counsel to represent the person.
If the defendant, however, understandingly waives representation by counsel, he or she shall execute a written waiver of such representation, which shall be filed in the case. If counsel is appointed, a reasonable time shall be accorded to counsel before the defendant shall be required to plead to the indictment or information on which he or she is to be arraigned or tried, or otherwise to proceed further.
