OEM INTEGRATION INSTRUCTIONS:
This device is intended only for OEM integrators under the following conditions:
The module must be installed in the host equipment such that 20 cm is maintained between the antenna
and users, and the transmitter module may not be co-located with any other transmitter or antenna. The
module shall be only used with the internal on-board antenna that has been originally tested and certified
with this module. External antennas are not supported. As long as these 3 conditions above are met,
further transmitter test will not be required.
However, the OEM integrator is still responsible for testing their end-product for any additional compliance
requirements required with this module installed (for example, digital device emissions, PC peripheral
requirements, etc.). The end-product may need Verification testing, Declaration of Conformity testing, a
Permissive Class II Change or new Certification. Please involve a FCC certification specialist in order to
determine what will be exactly applicable for the end-product.
Validity of using the module certification:
In the event that these conditions cannot be met (for example certain laptop configurations or co-location
with another transmitter), then the FCC/IC authorization for this module in combination with the host
equipment is no longer considered valid and the FCC ID/IC of the module cannot be used on the final
product. In these circumstances, the OEM integrator will be responsible for re-evaluating the end product
(including the transmitter) and obtaining a separate FCC authorization. In such cases, please involve a
FCC/IC certification specialist in order to determine if a Permissive Class II Change or new Certification is
required.
Upgrade Firmware:
The software provided for firmware upgrade will not be capable to affect any RF parameters as certified
for the FCC/IC for this module, in order to prevent compliance issues.
End product labeling:
This transmitter module is authorized only for use in device where the antenna may be installed such that
20 cm may be maintained between the antenna and users. The final end product must be labeled in a
visible area with the following: “Contains FCC ID: 2BOHY-922P2-M”.
Information that must be placed in the end user manual:
The OEM integrator has to be aware not to provide information to the end user regarding how to install
or remove this RF module in the user's manual of the end product which integrates this module. The end
user manual shall include all required regulatory information/warning as show in this manual.
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.
background
DO NOT list compliance to unintentional-radiator rules (Part 15 Subpart B/ICES-003) 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.
Explanation: This module meets the requirements of FCC part 15C(15.247), FCC part 15E(15.407).
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 No Antenna,The dipole antenna was used for the test.
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 not a limited module.
2.5 Trace antenna designs
For a modular transmitter with trace antenna designs, see the guidance in Question 11 of KDB
Publication 996369 D02 FAQ – Modules for Micro-Strip Antennas and traces. The integration 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;
background
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 trace antenna designs, and This manual has been shown the layout of
trace 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/IC (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, “Contains Transmitter Module FCC ID: 2BOHY-922P2-M Or Contains FCC ID:
2BOHY-922P2-M”.
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 a Dipole antenna, and the antenna utilizes an RA-SMA connector, making it
difficult to replace.

2.8 Label and compliance information
Grantees are responsible for the continued compliance of their modules to the FCC/IC 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 Transmitter Module FCC ID: 2BOHY-922P2-M Or Contains FCC ID:
2BOHY-922P2-M”.
2.9 Information on test modes and additional testing requirements5
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/IC
requirements.
Explanation: Top band can increase the utility of our modular transmitters by providing instructions that
simulates or characterizes a connection by enabling a transmitter.
2.10 Additional testing, Part 15 Subpart B/ICES-003 disclaimer
The grantee should include a statement that the modular transmitter is only FCC authorized for the
specific rule parts (i.e., FCC/IC transmitter rules) listed on the grant, and that the host product
manufacturer is responsible for compliance to any other FCC/IC 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/ICES-003 compliant (when it also contains unintentional-radiator digital circuity), then the
grantee shall provide a notice stating that the final host product still requires Part 15 Subpart B/ICES-003
compliance testing with the modular transmitter installed.
Explanation: The module without unintentional-radiator digital circuity, so the module does not require
an evaluation by FCC Part 15 Subpart B. The host shoule be evaluated by the FCC Subpart B.
