- Consult the dealer or an experienced radio/TV technician for help.
Radiation Exposure Statement:
This equipment complies with FCC radiation exposure limits set forth for an
uncontrolled environment.
This transmitter must not be co-located or operating in conjunction with any
other antenna or transmitter.
The availability of some specific channels and/or operational frequency bands
are country-dependent and are firmware programmed at the factory to match the
intended destination.
The firmware setting is not accessible by the end-user.
The final end product must be labelled in a visible area with the following:
“Contains Transmitter Module 2AZKP-ATS2819”
Requirement per KDB996369 D03
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).it specifically establish the 20dB Occupied Bandwidth, Peak Output
Power, Radiated Spurious Emission, Carrier Frequencies Separation, Restricted
Band of Operation and Band Edge (Out of Band Emissions), Hopping Channel
Number, Dwell Time, Pseudorandom Frequency, Hopping Sequence
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 one PCB antenna, the antenna cannot be replaced by other authorized antennas, and the gain of each replacement antenna is no more than 1dBi
Limited module procedures
If a modular transmitter is approved as a “limited module,” then the module
manufacturer isresponsible 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.
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:
- to the host product manufacturer, to define the application conditions (mobile, portable – xx cm from a person’s body)
- 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 5 mm between the radiator and your body.” This module is designed to comply with the FCC statement, FCC ID is: 2AZKP-ATS2819.
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 one PCB antenna, the antenna cannot be replaced by other authorized antennas, and the gain of each replacement antenna is no more than 1dBi
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: 2AZKP-ATS2819.
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 requirements.
Explanation: Dong Guan Gentech Instrument Electronic Co.,Ltd. can increase the
utility of our modular transmitters by providing instructions that simulates
or characterizes a connection by enabling a transmitter.
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
circuity), 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 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.
