Requirement per KDB996369 D03
2.2 List of applicable FCC rules
List the FCC rules that are applicable to the modular transmitter. These are the rules that
specifically establish the bands of operation, the power, spurious emissions, and operating
fundamental frequencies. DO NOT list compliance to unintentional-radiator rules (Part 15 Subpart
B) since that is not a condition of a module grant that is extended to a host manufacturer. See also
Section 2.10 below concerning the need to notify host manufacturers that further testing is
required.3
Explanation: This module meets the requirements of FCC part 15C(15.247).
2.3 Summarize the specific operational use conditions
Describe use conditions that are applicable to the modular transmitter, including for example any
limits on antennas, etc. For example, if point-to-point antennas are used that require reduction in
power or compensation for cable loss, then this information must be in the instructions. If the use
condition limitations extend to professional users, then instructions must state that this information
also extends to the host manufacturer’s instruction manual. In addition, certain information may
also be needed, such as peak gain per frequency band and minimum gain, specifically for master
devices in 5 GHz DFS bands.
Explanation: The EUT has PCB antenna, The antenna gain is -0.74dBi.
2.4 Limited module procedures
If a modular transmitter is approved as a “limited module,” then the module manufacturer is
responsible for approving the host environment that the limited module is used with. The
manufacturer of a limited module must describe, both in the filing and in the installation
instructions, the alternative means that the limited module manufacturer uses to verify that the
host meets the necessary requirements to satisfy the module limiting conditions. A limited module
manufacturer has the flexibility to define its alternative method to address the conditions that limit
the initial approval, such as: shielding, minimum signaling amplitude, buffered modulation/data
inputs, or power supply regulation. The alternative method could include that the limited module
manufacturer reviews detailed test data or host designs prior to giving the host manufacturer
approval. This limited module procedure is also applicable for RF exposure evaluation when it is
necessary to demonstrate compliance in a specific host. The module manufacturer must state how
control of the product into which the modular transmitter will be installed will be maintained such
that full compliance of the product is always ensured. For additional hosts other than the specific
host originally granted with a limited module, a Class II permissive change is required on the
module grant to register the additional host as a specific host also approved with the module.
Explanation: The module is a single module.

information shall include for the TCB review the integration instructions for the following aspects:
layout of trace design, parts list (BOM), antenna, connectors, and isolation requirements.
a) Information that includes permitted variances (e.g., trace boundary limits, thickness, length,
width, shape(s), dielectric constant, and impedance as applicable for each type of antenna);
b) Each design shall be considered a different type (e.g., antenna length in multiple(s) of frequency,
the wavelength, and antenna shape (traces in phase) can affect antenna gain and must be
considered);
c) The parameters shall be provided in a manner permitting host manufacturers to design the
printed circuit (PC) board layout;
d) Appropriate parts by manufacturer and specifications;
e) Test procedures for design verification; and
f) Production test procedures for ensuring compliance.
The module grantee shall provide a notice that any deviation(s) from the defined parameters of the
antenna trace, as described by the instructions, require that the host product manufacturer must
notify the module grantee that they wish to change the antenna trace design. In this case, a Class
II permissive change application is required to be filed by the grantee, or the host manufacturer
can take responsibility through the change in FCC ID (new application) procedure followed by a
Class II permissive change application.
Explanation: Yes, the module with PCB antenna designs, and this manual has been shown the
layout of design, antenna, connectors, and isolation requirements.
2.6 RF exposure considerations
It is essential for module grantees to clearly and explicitly state the RF exposure conditions that
permit a host product manufacturer to use the module. Two types of instructions are required for
RF exposure information: (1) to the host product manufacturer, to define the application conditions
(mobile, portable – xx cm from a person’s body); and (2) additional text needed for the host
product manufacturer to provide to end users in their end-product manuals. If RF exposure
statements and use conditions are not provided, then the host product manufacturer is required to
take responsibility of the module through a change in FCC ID (new application).
Explanation: This module complies with FCC RF radiation exposure limits set forth for an
uncontrolled environment; this equipment should be installed and operated with a minimum
distance of 20 centimeters between the radiator and your body." This module is designed to
comply with the FCC statement, FCC ID is: ROW-G47663U.

2.7 Antennas
A list of antennas included in the application for certification must be provided in the instructions.
For modular transmitters approved as limited modules, all applicable professional installer
instructions must be included as part of the information to the host product manufacturer. The
antenna list shall also identify the antenna types (monopole, PIFA, dipole, etc. (note that for
example an “omni-directional antenna” is not considered to be a specific “antenna type”)). For
situations where the host product manufacturer is responsible for an external connector, for
example with an RF pin and antenna trace design, the integration instructions shall inform the
installer that unique antenna connector must be used on the Part 15 authorized transmitters used
in the host product. The module manufacturers shall provide a list of acceptable unique
connectors.
Explanation: The EUT has External antenna (BT/BLE), PCB antenna (2.4G/5G WIFI), the antenna
gain is below.

2.8 Label and compliance information
Grantees are responsible for the continued compliance of their modules to the FCC rules. This
includes advising host product manufacturers that they need to provide a physical or e-label
stating “Contains FCC ID” with their finished product. See Guidelines for Labeling and User
Information for RF Devices – KDB Publication 784748.
Explanation: The host system using this module, should have label in a visible area indicated the
following texts: "Contains FCC ID: ROW-G47663U”
2.9 Information on test modes and additional testing requirements
Additional guidance for testing host products is given in KDB Publication 996369 D04 Module
Integration Guide. Test modes should take into consideration different operational conditions for a
stand-alone modular transmitter in a host, as well as for multiple simultaneously transmitting
modules or other transmitters in a host product.
The grantee should provide information on how to configure test modes for host product
evaluation for different operational conditions for a stand-alone modular transmitter in a host,
versus with multiple, simultaneously transmitting modules or other transmitters in a host.
Grantees can increase the utility of their modular transmitters by providing special means, modes,
or instructions that simulates or characterizes a connection by enabling a transmitter. This can
greatly simplify a host manufacturer’s determination that a module as installed in a host complies
with FCC requirements.
Explanation: Can increase the utility of our modular transmitters by providing instructions that
simulates or characterizes a connection by enabling a transmitter.

CHINA DRAGON TECHNOLOGY LIMITED Page 19

CDW-G47663U-00
2.10 Additional testing, Part 15 Subpart B disclaimer
The grantee should include a statement that the modular transmitter is only FCC authorized for the
specific rule parts (i.e., FCC transmitter rules) listed on the grant, and that the host product
manufacturer is responsible for compliance to any other FCC rules that apply to the host not
covered by the modular transmitter grant of certification. If the grantee markets their product as
being Part 15 Subpart B compliant (when it also contains unintentional-radiator digital circuit), then
the grantee shall provide a notice stating that the final host product still requires Part 15 Subpart B
compliance testing with the modular transmitter installed.
Explanation: The module without unintentional-radiator digital circuit, so the module does not
require an evaluation by FCC Part 15 Subpart B. The host should be evaluated by the FCC
Subpart B.
2.11 Note EMI Considerations
Note that a host manufacture is recommended to use D04 Module Integration Guide
recommending as "best practice" RF design engineering testing and evaluation in case non-linear
interactions generate additional non-compliant limits due to module placement to host
components or properties
Explanation: The host manufacturer is strongly recommended to confirm compliance with FCC
requirements for the transmitter when the module is installed in the host. This module is a
stand-alone modular. If the end product will involve the Multiple simultaneously transmitting
condition or different operational conditions for a stand-alone modular transmitter in a host, the
host manufacturer has to consult with the module manufacturer for the installation method in the
end system. Host manufacturer is recommended to use D04 Module Integration Guide. The final
host product may also need to be evaluated against FCC rule part 15 Subpart B (criteria for unint
entional radiators) in order to be properly authorized for operation as part 15B
2.12 How to make changes
Since. only Grantees are permitted to make permissive changes, it is recommended that module
manufactures provide contact information and some guidance to host providers in the integration
instructions if they expect their module will be used differently than granted.
Explanation: Module manufacturer contact: Tel: 13510082761,
