each 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

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:
