§ 15.205 Restricted bands of operation.
(a) Except as shown in paragraph (d) of this section, only spurious
emissions are permitted in any of the frequency bands listed below:
MHz MHz MHz GHz

13.36-13.41
^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 § 15.209. At frequencies equal to or less than
1000 MHz, compliance with the limits in § 15.209 shall be demonstrated using
measurement instrumentation employing a CISPR quasi-peak detector. Above
1000 MHz, compliance with the emission limits in § 15.209 shall be
demonstrated based on the average value of the measured emissions. The
provisions in § 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 § 15.213.
(4) Any equipment operated under the provisions of § 15.253, 15.255, and
15.256 in the frequency band 75-85 GHz, or § 15.257 of this part.
(5) Biomedical telemetry devices operating under the provisions of § 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 § 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 § 15.245 are exempt
from complying with the requirements of this section for the 48.15-48.35 GHz
and 72.225-72.525 GHz bands only, and shall not exceed the limits specified
in § 15.245(b).
(9) Devices operated in the 24.0-24.25 GHz band under § 15.249 are exempt
from complying with the requirements of this section for the 48.0-48.5 GHz
and 72.0-72.75 GHz bands only, and shall not exceed the limits specified in
§ 15.249(a).
(e) Harmonic emissions appearing in the restricted bands above 17.7 GHz from
field disturbance sensors operating under the provisions of § 15.245 shall
not exceed the limits specified in § 15.245(b).
