  §  90.217   Exemption from technical standards.

   Except as noted herein, transmitters used at stations licensed below
   800 MHz on any frequency listed in subparts B and C of this part or
   licensed on a business category channel above 800 MHz which have an
   output power not exceeding 120 milliwatts are exempt from the technical
   requirements set out in this subpart, but must instead comply with the
   following:

   (a) For equipment designed to operate with a 25 kHz channel bandwidth,
   the sum of the bandwidth occupied by the emitted signal plus the
   bandwidth required for frequency stability shall be adjusted so that
   any emission appearing on a frequency 40 kHz or more removed from the
   assigned frequency is attenuated at least 30 dB below the unmodulated
   carrier.

   (b) For equipment designed to operate with a 12.5 kHz channel
   bandwidth, the sum of the bandwidth occupied by the emitted signal plus
   the bandwidth required for frequency stability shall be adjusted so
   that any emission appearing on a frequency 25 kHz or more removed from
   the assigned frequency is attenuated at least 30 dB below the
   unmodulated carrier.

   (c) For equipment designed to operate with a 6.25 kHz channel
   bandwidth, the sum of the bandwidth occupied by the emitted signal plus
   the bandwidth required for frequency stability shall be adjusted so
   that any emission appearing on a frequency 12.5 kHz or more removed
   from the assigned frequency is attenuated at least 30 dB below the
   unmodulated carrier.

   (d) Transmitters may be operated in the continuous carrier transmit
   mode.

   (e) Transmitters used for wireless microphone operations and operating
   on frequencies allocated for Federal use must comply with the
   requirements of § 90.265(b).
