2.2 List of applicable FCC rules

List the FCC rules that are applicable to the modular transmitter. These are the rules that specificallyestablishthe bands of operation, the power, spurious emissions, and operating fundamental frequencies. DONOTlistcompliance to unintentional-radiator rules (Part 15 Subpart B) since that is not a condition of a modulegrantthat is extended to a host manufacturer. See also Section 2.10 below concerning the need tonotifyhostmanufacturers 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 anylimitsonantennas, etc. For example, if point-to-point antennas are used that require reduction inpowerorcompensation for cable loss, then this information must be in the instructions. If the use conditionlimitationsextend to professional users, then instructions must state that this information also extends tothehostmanufacturer’s instruction manual. In addition, certain information may also be needed, suchas peakgain per frequency band and minimum gain, specifically for master devices in 5 GHz DFS bands.

Explanation: The EUT has a FPC Antenna, and the antenna use a permanently attached antenna which is not replaceable.

2.4 Limited module procedures

If a modular transmitter is approved as a “limited module,” then the module manufacturer is responsiblefor approving the host environment that the limited module is used with. The manufacturer of alimitedmodule must describe, both in the filing and in the installation instructions, the alternative means thatthelimited module manufacturer uses to verify that the host meets the necessary requirements tosatisfythemodule limiting conditions.

A limited module manufacturer has the flexibility to define its alternative method to address theconditionsthat limit the initial approval, such as: shielding, minimum signaling amplitude, buffered modulation/datainputs, or power supply regulation. The alternative method could include that the limitedmodulemanufacturer 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 todemonstrate compliance in a specific host. The module manufacturer must state how control of theproductinto which the modular transmitter will be installed will be maintained such that full complianceof theproduct is always ensured. For additional hosts other than the specific host originally granted withalimitedmodule, a Class II permissive change is required on the module grant to register the additional host asaspecific 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 KDBPublication996369 D02 FAQ – Modules for Micro-Strip Antennas and traces. The integration informationshall includefor 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 printedcircuit(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 theantennatrace, as described by the instructions, require that the host product manufacturer must notify themodulegrantee that they wish to change the antenna trace design. In this case, a Class II permissivechangeapplication is required to be filed by the grantee, or the host manufacturer can take responsibility throughthechange 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 ahostproduct manufacturer to use the module. Two types of instructions are required for RF exposureinformation:(1) to the host product manufacturer, to define the application conditions (mobile, portable –xx cmfromaperson’s body); and (2) additional text needed for the host product manufacturer to provide toendusersintheir end-product manuals. If RF exposure statements and use conditions are not provided, thenthehostproduct manufacturer is required to take responsibility of the module through a change in FCCID(newapplication).

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 20centimetersbetween the radiator and your body.” This module is designed to comply with the FCC statement, FCCIDis: 2AYHE-2403C

2.7 Antennas

A list of antennas included in the application for certification must be provided in the instructions. For modulartransmitters approved as limited modules, all applicable professional installer instructions must beincludedaspart of the information to the host product manufacturer. The antenna list shall also identify theantennatypes (monopole, PIFA, dipole, etc. (note that for example an “omni-directional antenna”is not consideredto be a specific “antenna type”)).

For situations where the host product manufacturer is responsible for an external connector, for examplewithan RF pin and antenna trace design, the integration instructions shall inform the installer that uniqueantennaconnector must be used on the Part 15 authorized transmitters used in the host product. Themodulemanufacturers shall provide a list of acceptable unique connectors.

Explanation: The EUT has FPC Antenna, and the antenna use a permanently attached antenna which is unique.

2.8 Label and compliance information

Grantees are responsible for the continued compliance of their modules to the FCC rules. This includesadvising host product manufacturers that they need to provide a physical or e-label stating “ContainsFCCID” with their finished product. See Guidelines for Labeling and User Information for RF Devices –KDBPublication 784748.

Explanation:The host system using this module, should have label in a visible area indicated the following texts: “Contains FCC ID: 2AYHE-2403C, Contains IC: 26839-2403C”

2.9 Information on test modes and additional testing requirements5

Additional guidance for testing host products is given in KDB Publication 996369 D04 ModuleIntegrationGuide. Test modes should take into consideration different operational conditions for a stand-alonemodulartransmitter in a host, as well as for multiple simultaneously transmitting modules or other transmittersinahost product.

The grantee should provide information on how to configure test modes for host product evaluationfordifferent operational conditions for a stand-alone modular transmitter in a host, versus withmultiple,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 greatlysimplifyahost manufacturer’s determination that a module as installed in a host complies with FCC 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 disclaimer

The grantee should include a statement that the modular transmitter is only FCC authorized for thespecificrule parts (i.e., FCC transmitter rules) listed on the grant, and that the host product manufacturerisresponsible for compliance to any other FCC rules that apply to the host not covered by themodulartransmitter grant of certification. If the grantee markets their product as being Part 15 Subpart Bcompliant(when it also contains unintentional-radiator digital circuity), then the grantee shall provide a noticestatingthat the final host product still requires Part 15 Subpart B compliance testing with the modular transmitterinstalled.

Explanation: The module without unintentional-radiator digital circuity, so the module does not require an evaluation by FCC Part 15 Subpart B. The hostshoule be evaluated by the FCC Subpart B.

The OEM must certify the final end product to comply with unintentional radiators (FCC Sections 15.107 and 15.109) before declaring compliance of the final product to Part 15 of the FCC rules and regulations. Integration into devices that are directly or indirectly connected to AC lines must add with Class II Permissive Change.

The OEM must comply with the FCC labeling requirements. If the module’s label is not visiblewhen installed,then an additional permanent label must be applied on the outside of the finishedproduct which states: “Contains transmitter module FCC ID: 2AYHE-2403C”. Additionally, thefollowing statement should be included on the label and in the final product’s user manual:

“This device complies with Part 15 of the FCC Rules. Operation is subject to the following twoconditions:

(1) This device may not cause harmful interferences, and

(2) this device must accept any interference received, including interference that may causeundesired operation.”

The module is limited to installation in mobile or fixed applications. Separate approval is requiredfor all other operating configurations, including portable configuration with respect to Part 2.1093and different antenna configurations.

A module or modules can only be used without additional authorizations if they have been testedand granted under the same intended end‐use operational conditions, including simultaneous transmission operations.

When they have not been tested and granted in this manner, additional testing and/or FCCapplication filing may be required. The most straightforward approach to address additional testing conditions is to have the grantee responsible for the certification of at least one of themodules submit a permissive change application.

When having a module grantee file a permissive change is not practical or feasible, the followingguidance provides some additional options for host manufacturers. Integrations using modules where additional testing and/or FCC application filing(s) may be required are: (A) a module usedin devices requiring additional RF exposure compliance information (e.g., MPE evaluation or SARtesting); (B) limited and/or split modules not meeting all of the module requirements; and (C) simultaneous transmissions for independent collocated transmitters not previously grantedtogether.

This Module is full modular approval, it is limited to OEM installation ONLY. Integration into devices that are directly or indirectly connected to AC lines must add with Class II Permissive Change. (OEM) Integrator has to assure compliance of the entire end product includethe integrated Module. Additional measurements (15B) and/or equipment authorizations (e.g. Verification) may need to be addressed depending on co-location or simultaneous transmissionissues if applicable. (OEM) Integrator is reminded to assure that these installation instructions will not be made available to the end user
