Section 15.212 Modular Transmitters
Request for Modular Approval Request for Limited Modular Approval
Requirements EUT Conditions Comply (Y/N)
Single Modular Approval Requirements
1 The radio elements of the modular CGI is submitting via Limited Modular N
transmitter must have their own Approval (LMA). Additionally, the
shielding. The physical crystal and Marvell Module will be tested with the
tuning capacitors may be located host and Class 2 Permissive Change
external to the shielded radio elements. (C2PC) will be filed with FCC.
2 The modular transmitter must have none Y
buffered modulation/data inputs (if such
inputs are provided) to ensure that the
module will comply with Part 15
requirements under conditions of
excessive data rates or over-modulation.
3 The modular transmitter must have its none Y
own power supply regulation.
4 The modular transmitter must comply none Y
with the antenna and transmission
system requirements of Sections 15.203,
15.204(b) and 15.204(c). The antenna
must either be permanently attached or
employ a “unique” antenna coupler (at
all connections between the module and
the antenna, including the cable). The
“professional installation” provision of
Section 15.203 is not applicable to
modules but can apply to limited
modular approvals under paragraph (b)
of this section.
5 The modular transmitter must be tested none Y
in a stand-alone configuration, i.e., the
module must not be inside another
device during testing for compliance
with Part 15 requirements. Unless the
transmitter module will be battery
powered, it must comply with the AC
line conducted requirements found in
Section 15.207. AC or DC power lines
and data input/output lines connected to
the module must not contain ferrites,
unless they will be marketed with the
module (see Section 15.27(a)). The
length of these lines shall be the length
typical of actual use or, if that length is
unknown, at least 10 centimeters to
insure that there is no coupling between
the case of the module and supporting

equipment. Any accessories, peripherals,
or support equipment connected to the
module during testing shall be
unmodified and commercially available
(see Section 15.31(i)).
6 The modular transmitter must be none Y
equipped with either a permanently
affixed label or must be capable of
electronically displaying its FCC
identification number.
(A) If using a permanently affixed label, the
modular transmitter must be labeled with its own
FCC identification number, and, if the FCC
identification number is not visible when the
module is installed inside another device, then
the outside of the device into which the module is
installed must also display a label referring to
the enclosed module. This exterior label can use
wording such as the following: “Contains
Transmitter Module
FCC ID: XYZMODEL1” or “Contains FCC ID:
XYZMODEL1.” Any similar wording
that expresses the same meaning may be used.
The Grantee may either provide such a label, an
example of which must be included in the
application for equipment
authorization, or, must provide adequate
instructions along with the module which explain
this requirement. In the latter case, a copy of
these instructions must be included in the
application for equipment authorization.
(B) If the modular transmitter uses an electronic
display of the FCC identification number, the
information must be readily accessible and
visible on the modular transmitter or on the
device in which it is installed. If the module is
installed inside another device, then the outside
of the device into which the module is installed
must display a label referring to the enclosed
module. This exterior label can use wording such
as the following:
“Contains FCC certified transmitter module(s).”
Any similar wording that expresses the same
meaning may be used. The user manual must
include instructions on how to access the
electronic display. A copy of these instructions
must be included in the application for
equipment authorization.
7 The modular transmitter must comply none Y
with any specific rules or operating
requirements that
ordinarily apply to a complete
transmitter and the manufacturer must
provide adequate instructions along with
the module to explain any such
requirements. A copy of these
instructions must be included in the
application for equipment authorization.

8 The modular transmitter must comply none Y
with any applicable RF exposure
requirements in its final configuration.
A limited modular approval may be granted for single or split modular transmitters that do not comply with
all of the above requirements, e.g., shielding, minimum signaling amplitude, buffered modulation/data inputs, or
power supply regulation, if the manufacturer can demonstrate by alternative means in the application for
equipment authorization that the modular transmitter meets all the applicable Part 15 requirements under the
operating conditions in which the transmitter will be used. Limited modular approval also may be granted in
those instances where compliance with RF exposure rules is demonstrated only for particular product
configurations. The applicant for certification must state how control of the end product into which the module
will be installed will be maintained such that full compliance of the end product is always ensured.
