The conservatee shall be present at the hearing unless he is unable to attend by reason of physical or other inability, and that inability is established to the satisfaction of the court. If the conservatee is found to be unable to attend, the court shall, subject to rules of court, order an investigation to be conducted to assure the conservatee does not object to the conservatorship unless the court believes, in its discretion, that the interests of the conservatee are adequately protected by counsel representing the conservatee.
