§  74.550   Equipment authorization.

   Each authorization for aural broadcast STL, ICR, and booster stations
   shall require the use of equipment which has received a grant of
   certification or authorized under a Supplier's Declaration of
   Conformity. Equipment which has not been approved under the equipment
   authorization program and which was in service prior to July 1, 1993,
   may be retained solely for temporary uses necessary to restore or
   maintain regular service provided by approved equipment, because the
   main or primary unit has failed or requires servicing. Such temporary
   uses may not interfere with or impede the establishment of other aural
   broadcast auxiliary links and may not occur during more than 720
   cumulative hours per year. Should interference occur, the licensee must
   take all steps necessary to eliminate it, up to and including cessation
   of operation of the auxiliary transmitter. All unapproved equipment
   retained for temporary use must have been in the possession of the
   licensee prior to July 1, 1993, and may not be obtained from other
   sources. Equipment designed exclusively for fixed operation shall be
   authorized under Supplier's Declaration of Conformity procedure. The
   equipment authorization procedures are contained in subpart J of part 2
   of this chapter.

   Note 1 to § 74.550: The Declaration of Conformity procedure has been
   replaced by Supplier's Declaration of Conformity. Equipment previously
   authorized under subpart J of part 2 of this chapter may remain in use.
   See § 2.950 to this chapter.

   Note 2 to § 74.550: Consistent with the note to § 74.502(a),
   grandfathered equipment in the 942-944 MHz band and STL/ICR users of
   these frequencies in Puerto Rico are also required to come into
   compliance by July 1, 1993. The backup provisions described above apply
   to these stations also.
