The arbitrator shall appoint a time and place for the hearing and notify the parties in writing personally or by registered or certified mail not less than eight days before the hearing. The arbitrator may adjourn or postpone the hearing. The court, upon application of any party, may direct the arbitrator to proceed promptly with the hearing and determination of the controversy.

The hearing shall be conducted by all the arbitrators, but a majority may determine any question and render an award. (f) Waiver.
