FCC 15.121 Revised as of December 4, 2012
Goto Year:2011 |
§ 15.121 Scanning receivers and frequency converters used with scanning
(a) Except as provided in paragraph (c) of this section, scanning
receivers and frequency converters designed or marketed for use with
scanning receivers, shall:
(1) Be incapable of operating (tuning), or readily being altered by the
user to operate, within the frequency bands allocated to the Cellular
Radiotelephone Service in part 22 of this chapter (cellular telephone
bands). Scanning receivers capable of “readily being altered by the
user” include, but are not limited to, those for which the ability to
receive transmissions in the cellular telephone bands can be added by
clipping the leads of, or installing, a simple component such as a
diode, resistor or jumper wire; replacing a plug-in semiconductor chip;
or programming a semiconductor chip using special access codes or an
external device, such as a personal computer. Scanning receivers, and
frequency converters designed for use with scanning receivers, also
shall be incapable of converting digital cellular communication
transmissions to analog voice audio.
(2) Be designed so that the tuning, control and filtering circuitry is
inaccessible. The design must be such that any attempts to modify the
equipment to receive transmissions from the Cellular Radiotelephone
Service likely will render the receiver inoperable.
(b) Except as provided in paragraph (c) of this section, scanning
receivers shall reject any signals from the Cellular Radiotelephone
Service frequency bands that are 38 dB or lower based upon a 12 dB
SINAD measurement, which is considered the threshold where a signal can
be clearly discerned from any interference that may be present.
(c) Scanning receivers and frequency converters designed or marketed
for use with scanning receivers, are not subject to the requirements of
paragraphs (a) and (b) of this section provided that they are
manufactured exclusively for, and marketed exclusively to, entities
described in 18 U.S.C. 2512(2), or are marketed exclusively as test
equipment pursuant to § 15.3(dd).
(d) Modification of a scanning receiver to receive transmissions from
Cellular Radiotelephone Service frequency bands will be considered to
constitute manufacture of such equipment. This includes any individual,
individuals, entity or organization that modifies one or more scanners.
Any modification to a scanning receiver to receive transmissions from
the Cellular Radiotelephone Service frequency bands voids the
certification of the scanning receiver, regardless of the date of
manufacture of the original unit. In addition, the provisions of
§ 15.23 shall not be interpreted as permitting modification of a
scanning receiver to receiver Cellular Radiotelephone Service
(e) Scanning receivers and frequency converters designed for use with
scanning receivers shall not be assembled from kits or marketed in kit
form unless they comply with the requirements in paragraph (a) through
(c) of this section.
(f) Scanning receivers shall have a label permanently affixed to the
product, and this label shall be readily visible to the purchaser at
the time of purchase. The label shall read as follows: WARNING:
MODIFICATION OF THIS DEVICE TO RECEIVE CELLULAR RADIOTELEPHONE SERVICE
SIGNALS IS PROHIBITED UNDER FCC RULES AND FEDERAL LAW.
(1) “Permanently affixed” means that the label is etched, engraved,
stamped, silkscreened, indelible printed or otherwise permanently
marked on a permanently attached part of the equipment or on a
nameplate of metal, plastic or other material fastened to the equipment
by welding, riveting, or permanent adhesive. The label shall be
designed to last the expected lifetime of the equipment in the
environment in which the equipment may be operated and must not be
readily detachable. The label shall not be a stick-on, paper label.
(2) When the device is so small that it is not practicable to place the
warning label on it, the information required by this paragraph shall
be placed in a prominent location in the instruction manual or pamphlet
supplied to the user and shall also be placed on the container in which
the device is marketed. However, the FCC identifier must be displayed
on the device.
