(b) Notice.
(1) Personal appearance either by physical presence or audio-video communication technology of any person in a hearing before the court shall obviate the necessity of serving process on that person.
(2) The clerk of the court shall give notice of the time and place of the arraignment to the parent or guardian of the child and the superintendent of the detention center by:
(A) summons;
(B) written notice; or
(C) telephone notice.
(3) The superintendent of the detention center, or designee, also shall verify that a diligent effort has been made to notify the parent or guardian of the child of the time and place of the arraignment.
(4) Failure of notice to the parent or guardian, or nonattendance of the parent or guardian at the hearing, shall not invalidate the proceeding.
