§  95.335   Operation of non-certified transmitters prohibited.

   Except as provided in paragraph (a) of this section, no person shall
   operate a transmitter in any Personal Radio Service unless it is a
   certified transmitter; that is, a transmitter of a type which has
   obtained a grant of equipment certification for that service, pursuant
   to part 2, subpart J of this chapter. Use of a transmitter that is not
   FCC-certified voids the user's authority to operate that station. See
   sections 302(a), (b), and (e) of the Communications Act (47 U.S.C.
   302(a), (b), and (e)).

   (a) Exceptions. Under certain exceptions, non-certified Personal Radio
   Service transmitters, or transmitters certified for use in the land
   mobile radio services may be operated. Any such exceptions applicable
   to stations in a Personal Radio Service are set forth in the subpart
   governing that specific service. See e.g., § § 95.735 and 95.1735.

   (b) Revoked or withdrawn certification. In the event that the FCC
   revokes or withdraws a grant of equipment certification for a type of
   Personal Radio Service transmitter, existing transmitters already in
   service may continue to be operated unless and until the FCC determines
   otherwise and gives Public Notice of that decision.

   (c) Grantee permissible modifications. Only the grantee of the
   equipment certification may modify the design of a certified Personal
   Radio Service transmitter type, and then only pursuant to and in full
   compliance with the requirements and procedures for permissible changes
   and modifications in part 2 of this chapter. See § § 2.932 and 2.1043 of
   this chapter.
