Sec.  101.139  Authorization of transmitters.

    (a) Unless specified otherwise, transmitters used in the private 
operational fixed and common carrier fixed point-to-point microwave and 
point-to-multipoint services under this part must be a type that has 
been verified for compliance.
    (b) Any manufacturer of a transmitter to be produced for use under 
the rules of this part may request certification or obtain verification 
by following the applicable procedures set forth in part 2 of this 
chapter.
    (c) Certification for an individual transmitter may also be 
requested by an applicant for a station authorization, pursuant to the 
procedures set forth in part 2 of this chapter.
    (d) A transmitter presently shown on an instrument of authorization, 
which operates on an assigned frequency in the 890-940 MHz band and has 
not been certificated, may continue to be used by the licensee without 
certification provided such transmitter continues otherwise to comply 
with the applicable rules and regulations of the Commission.
    (e) Certification or verification is not required for portable 
transmitters operating with peak output power not greater than 250 mW. 
If operation of such equipment causes harmful interference the FCC may, 
at its discretion, require the licensee to take such corrective action 
as is necessary to eliminate the interference.
