Sec. 2. When a criminal case is set for such pre-trial hearing, any such preliminary matters not raised or filed seven days before the hearing will not thereafter be allowed to be raised or filed, except by permission of the court for good cause shown; provided that the defendant shall have sufficient notice of such hearing to allow him not less than 10 days in which to raise or file such preliminary matters. The record made at such pre-trial hearing, the rulings of the court and the exceptions and objections thereto shall become a part of the trial record of the case upon its merits.
Sec. 3. The notice mentioned in Section 2 above shall be sufficient if given in any one of the following ways:
(1) By announcement made by the court in open court in the presence of the defendant or his attorney of record;
(2) By personal service upon the defendant or his attorney of record;
(3) By mail to either the defendant or his attorney of record deposited by the clerk in the mail at least six days prior to the date set for hearing. If the defendant has no attorney of record such notice shall be addressed to defendant at the address shown on his bond, if the bond shows such an address, and if not, it may be addressed to one of the sureties on his bond. If the envelope containing the notice is properly addressed, stamped and mailed, the state will not be required to show that it was received.
