If a defendant has submitted to the court a written statement with his bail, as provided in section 2.870, it constitutes a waiver of hearing and a consent to judgment by the court, declaring a forfeiture of bail on the basis of the statement, and any testimony or written statement of the arresting officer or other witnesses which may be presented to the court. If the defendant requests a hearing or if, under section 2.880, the court directs that a hearing be held, the court shall fix the date and time for hearing and, unless notice is waived, shall, at least five days in advance of the hearing, mail to the defendant notice of the date and time.
