   transmitter utilized for operation under this part and each transmitter
   marketed as set forth in  Sec. 2.803 of this chapter must be of a type which has
   been certificated for use under this part.

   (1) Effective October 16, 2002, except in the 1427–1432 MHz band, an
   equipment approval may no longer be obtained for in-hospital medical
   telemetry equipment operating under the provisions of this part. The
   requirements for obtaining an approval for medical telemetry equipment after
   this date are found in subpart H of part 95 of this chapter.

   (2) Any manufacturer of radio transmitting equipment (including signal
   boosters) to be used in these services may request certification for such
   equipment following the procedures set forth in subpart J of part 2 of this
   chapter. Certification for an individual transmitter or signal booster also
   may be requested by an applicant for a station authorization by following
   the procedure set forth in part 2 of this chapter. Such equipment if
   approved will be individually enumerated on the station authorization.

   (b) Certification is not required for the following:

   (1) Transmitters used in developmental operations in accordance with subpart
   Q.

   (2) Transmitters used for police zone and interzone stations authorized as
   of January 1, 1965.

   (3) Transmitting equipment used in the band 1427–1435 MHz.

   using the equipment's external operation controls.

   (f) Except as provided in paragraph (g) of this section, transmitters
   designed to operate above 25 MHz that have been approved prior to January
   15, 1988, and that permit the operator, by using external controls, to
   program the transmitter's operating frequencies, shall not be manufactured
   in, or imported into the United States after March 15, 1988. Marketing of
   these transmitters shall not be permitted after March 15, 1989.

   (g) Transmitters having frequency programming capability and that are
   designed to operate above 25 MHz are exempt from paragraphs (e) and (f) of
   this section if the design of such transmitters:

   the operator must be internally modified to place the equipment in the
   programmable mode. Further, while in the programmable mode, the equipment
   shall not be capable of transmitting. The procedures for making the
   modification and altering the frequency program shall not be made available
   with the operating information normally supplied to the end user of the
   equipment; or

   (2) Requires the tramsitter to be programmed for frequencies through
   controls normally inaccessible to the operator; or

   (3) Requires equipment to be programmed for frequencies through use of
   external devices or specifically programmed modules made available only to
   service/maintenance personnel; or

   (4) Requires equipment to be programmed through cloning (copying a program
   directly from another transmitter) using devices and procedures made
   available only to service/maintenance personnel.

   (h) The requirements of paragraphs (e), (f), and (g) of this section shall
   not apply if:
