§ 15.15 General
ments.
technical
require-
(a) An intentional or unintentional
radiator shall be constructed in accord-
ance with good engineering design and
manufacturing practice. Emanations
from the device shall be suppressed as
much as practicable, but in no case
shall the emanations exceed the levels
specified in these rules.
(b) Except as follows, an intentional
or unintentional radiator must be con-
structed such that the adjustments of
any control that is readily accessible
by or intended to be accessible to the
user will not cause operation of the de-
vice in violation of the regulations. Ac-
cess BPL equipment shall comply with
the applicable standards at the control
adjustment that is employed. The
measurement report used in support of
an application for Certification and the
user instructions for Access BPL equip-
ment shall clearly specify the user-or
installer-control settings that are re-
quired for conformance with these reg-
ulations.
(c) Parties responsible for equipment
compliance should note that the limits
specified in this part will not prevent
harmful interference under all cir-
cumstances. Since the operators of
part 15 devices are required to cease op-
eration should harmful interference
occur to authorized users of the radio
frequency spectrum, the parties re-
sponsible for equipment compliance are
encouraged to employ the minimum
field strength necessary for commu-
§ 15.19
nications, to provide greater attenu-
ation of unwanted emissions than re-
quired by these regulations, and to ad-
vise the user as to how to resolve
harmful interference problems (for ex-
ample, see § 15.105(b)).

compliance are advised to consider the
proximity and the high power of non-
Government licensed radio stations,
such as broadcast, amateur, land mo-
bile, and non-geostationary mobile sat-
ellite feeder link earth stations, and of
U.S. Government radio stations, which
could include high-powered radar sys-
tems, when choosing operating fre-
quencies during the design of their
equipment so as to reduce the suscepti-
bility for receiving harmful inter-
ference. Information on non-Govern-
ment use of the spectrum can be ob-
tained by consulting the Table of Fre-
quency Allocations in § 2.106 of this
chapter.
(b) Information on U.S. Government
operations can be obtained by con-
tacting: Director, Spectrum Plans and
Policy, National Telecommunications
and Information Administration, De-
partment of Commerce, Room 4096,
Washington, DC 20230.

two or more sections connected by
wires and marketed together, the
statement specified under paragraph
(a) of this section is required to be af-
fixed only to the main control unit.
47 CFR Ch. I (10–1–09 Edition)
(5) When the device is so small or for
such use that it is not practicable to
place the statement specified under
paragraph (a) of this section 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 or, alternatively,
shall be placed on the container in
which the device is marketed. However,
the FCC identifier or the unique identi-
fier, as appropriate, must be displayed
on the device.
(b) Products subject to authorization
under a Declaration of Conformity
shall be labelled as follows:
(1) The label shall be located in a
conspicuous location on the device and
shall contain the unique identification

the following logo:
(i) If the product is authorized based
on testing of the product or system; or
(ii) If a personal computer is author-
ized based on assembly using sepa-
rately authorized components, in ac-
cordance with § 15.101(c)(2) or (c)(3), and
the resulting product is not separately
tested:
(2) Label text and information should
be in a size of type large enough to be
readily legible, consistent with the di-
mensions of the equipment and the

such as for a CPU board or a plug-in
circuit board peripheral device, the
text associated with the logo may be
placed in a prominent location in the
instruction manual or pamphlet sup-
plied to the user. However, the unique
identification (trade name and model
number) and the logo must be dis-
played on the device.
(4) The label shall not be a stick-on,
paper label. The label on these prod-
ucts shall be permanently affixed to
the product and shall be readily visible
to the purchaser at the time of pur-
chase, as described in § 2.925(d) of this
chapter. ‘‘Permanently affixed’’ means
that the label is etched, engraved,
stamped, silkscreened, indelibly print-
ed, 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
a permanent adhesive. The label must
be designed to last the expected life-
time of the equipment in the environ-
ment in which the equipment may be
operated and must not be readily de-
tachable.
(c) [Reserved]
(d) Consumer electronics TV receiv-
ing devices, including TV receivers,
videocassette recorders, and similar de-
vices, that incorporate features in-
tended to be used with cable television
service, but do not fully comply with
the technical standards for cable ready
equipment set forth in § 15.118, shall
not be marketed with terminology that
describes the device as ‘‘cable ready’’
or ‘‘cable compatible,’’ or that other-
wise conveys the impression that the
device is fully compatible with cable
service. Factual statements about the
various features of a device that are in-
tended for use with cable service or the
quality of such features are acceptable
so long as such statements do not
imply that the device is fully compat-
ible with cable service. Statements re-
lating to product features are generally
acceptable where they are limited to
one or more specific features of a de-
vice, rather than the device as a whole.
This requirement applies to consumer
TV receivers, videocassette recorders
and similar devices manufactured or
§ 15.25
imported for sale in this country on or
after October 31, 1994.

§ 15.21 Information to user.
The users manual or instruction
manual for an intentional or uninten-
tional radiator shall caution the user
that changes or modifications not ex-
pressly approved by the party respon-
sible for compliance could void the
user’s authority to operate the equip-
ment. In cases where the manual is
provided only in a form other than
paper, such as on a computer disk or
over the Internet, the information re-
quired by this section may be included
in the manual in that alternative form,
provided the user can reasonably be ex-
pected to have the capability to access
information in that form.

ploy good engineering practices to
meet the specified technical standards
to the greatest extent practicable. The
provisions of § 15.5 apply to this equip-
ment.
