   ^1Until February 1, 1999, this restricted band shall be 0.490–0.510 MHz.

   ^2Above 38.6

   (b) Except as provided in paragraphs (d) and (e) of this section, the field
   strength of emissions appearing within these frequency bands shall not
   exceed the limits shown in  Sec. 15.209. At frequencies equal to or less than
   1000 MHz, compliance with the limits in  Sec. 15.209 shall be demonstrated using
   measurement instrumentation employing a CISPR quasi-peak detector. Above
   1000  MHz,  compliance  with  the  emission limits in  Sec. 15.209 shall be
   demonstrated based on the average value of the measured emissions. The
   provisions in  Sec. 15.35 apply to these measurements.

   (c) Except as provided in paragraphs (d) and (e) of this section, regardless
   of  the field strength limits specified elsewhere in this subpart, the
   provisions of this section apply to emissions from any intentional radiator.

   (d) The following devices are exempt from the requirements of this section:

   (1) Swept frequency field disturbance sensors operating between 1.705 and 37
   MHz  provided  their  emissions only sweep through the bands listed in
   paragraph  (a)  of  this  section, the sweep is never stopped with the
   fundamental  emission within the bands listed in paragraph (a) of this
   section, and the fundamental emission is outside of the bands listed in
   paragraph  (a) of this section more than 99% of the time the device is
   actively transmitting, without compensation for duty cycle.

   (2) Transmitters used to detect buried electronic markers at 101.4 kHz which
   are employed by telephone companies.

   (3) Cable locating equipment operated pursuant to  Sec. 15.213.

   (4) Any equipment operated under the provisions of  Sec.  Sec. 15.253, 15.255 or
   15.257.

   (5) Biomedical telemetry devices operating under the provisions of  Sec. 15.242
   of this part are not subject to the restricted band 608–614 MHz but are
   subject to compliance within the other restricted bands.

   (6) Transmitters operating under the provisions of subparts D or F of this
   part.

   (7) Devices operated pursuant to  Sec. 15.225 are exempt from complying with this
   section for the 13.36–13.41 MHz band only.

   (8) Devices operated in the 24.075–24.175 GHz band under  Sec. 15.245 are exempt
   from complying with the requirements of this section for the 48.15–48.35 GHz
   and 72.22572.525 GHz bands only, and shall not exceed the limits specified
   in  Sec. 15.245(b).

   (9) Devices operated in the 24.0–24.25 GHz band under  Sec. 15.249 are exempt
   from complying with the requirements of this section for the 48.0–48.5 GHz
   and 72.072.75 GHz bands only, and shall not exceed the limits specified in
    Sec. 15.249(a).

   (e) Harmonic emissions appearing in the restricted bands above 17.7 GHz from
   field disturbance sensors operating under the provisions of  Sec. 15.245 shall
   not exceed the limits specified in  Sec. 15.245(b).
