FCC Statement
This equipment has been tested and found to comply with the limits for a Class B digital
device, pursuant to part 15 of the FCC rules. These limits are designed to provide reasonable
protection against harmful interference in a residential installation. This equipment
generates, uses and can radiate radio frequency energy and, if not installed and used in
accordance with the instructions, may cause harmful interference to radio communications.
However, there is no guarantee that interference will not occur in a particular installation.
If this equipment does cause harmful interference to radio or television reception, which
can be determined by turning the equipment off and on, the user is encouraged to try to
correct the interference by one or more of the following measures:
-Reorient or relocate the receiving antenna.
-Increase the separation between the equipment and receiver.
-Connect the equipment into an outlet on a circuit different from that to which the receiver
is connected.
-Consult the dealer or an experienced radio/TV technician for help.
This equipment complies with Part 15 of the FCC Rules. Operation is subject to the following
two conditions:
(1) This device may not cause harmful interference, and
(2) This device must accept any interference received, including interference that may cause
undesired operation.
Any changes or modifications not expressly approved by the party responsible for compliance
could void the user’s authority to operate the equipment.
2.2
This module has been assessed against the following FCC rule parts: CFR 47 FCC Part 15 C
(15.247, DTS and DSS) and CFR 47 FCC Part 15 E (NII). It is applicable to the modular
transmitter
2.3
This radio transmitter 2AC23-WKCT1H has been approved by Federal Communications Commission
to operate with the antenna types listed below, with the maximum permissible gain indicated.
Antenna types not included in this list that have a gain greater than the maximum gain
indicated for any type listed are strictly prohibited for use with this device.
The concrete contents to check are the following three points.
１) Maximum antenna gains are shown in item 2.8 below.
２) Should be installed so that the end user cannot modify the antenna
３) Feed line should be designed in 50ohm
Fine-tuning of return loss etc. can be performed using a matching network.
The antenna shall not be accessible for modification or change by the end user.

2.4
The module complies with FCC Part 15.247 / Part 15.407 and apply for Single module approval.
2.5
Trace antenna designs: Not applicable, the antenna conector for this module are integrated
into the module. Use of external antennas or antennas integrated into the host circuit board
are not an option.
2.6
This equipment complies with FCC radiation exposure limits set forth for an uncontrolled
environment. This equipment should be installed and operated with a minimum distance of
20cm between the radiator & your body. This transmitter must not be co-located or operating
in conjunction with any other antenna or transmitter.
2.7
The following antennas have been certified for use with this module.
Only antennas of the same type with equal or lower gain may also be used with this module.
Other types of antennas and/or higher gain antennas may require the additional authorization
for operation. The installer should use unique antenna connector and Antenna types not
included in this list that have a gain greater than the maximum gain indicated for any type
listed are strictly prohibited for use with this device. The manufacturer of module will
inform installer to meet with the FCC part 15.203 in the warning part.
Antenna Specification list below:
2.8
Please notice that 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 “Contains FCC ID: 2AC23-WKCT1H”; any similar wording that expresses
the same meaning may be used.

2.9
Testing of the host product with all the transmitters installed – referred to as the
composite investigation test- is recommended, to verify that the host product meets all
the applicable FCC rules. The radio spectrum is to be investigated with all the transmitters
in the final host product functioning to determine that no emissions exceed the highest
limit permitted for any one individual transmitter as required by Section 2.947(f). The
host manufacturer is responsible to ensure that when their product operates as intended
it does not have any emissions present that are out of compliance that were not present
when the transmitters were tested individually.
If the modular transmitter has been fully tested by the module grantee on the required number
of channels, modulation types, and modes, it should not be necessary for the host installer
to re-test all the available transmitter modes or settings. It is recommended that the host
product manufacturer, installing the modular transmitter, perform some investigative
measurements to confirm that the resulting composite system does not exceed the spurious
emissions limits or band edge limits (e.g., where a different antenna may be causing
additional emissions).
The testing should check for emissions that may occur due to the intermixing of emissions
with the other transmitters, digital circuitry, or due to physical properties of the host
product (enclosure). This investigation is especially important when integrating multiple
modular transmitters where the certification is based on testing each of them in a
stand-alone configuration.
2.10
Any company of the host device which install this modular should perform the test of radiated
& conducted emission and spurious emission etc. according to FCC Part 15C: 15.247 and 15.209
& 15.207, part 15 E 15.407,15B class B requirement, only if the test result comply with
FCC part 15C: 15.247 and 15.209 & 15.207, part 15 E 15.407,15B class B requirement. Then
the host can be sold legally.
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.
2.11
The host manufacturer is recommended to use FCC KDB 996369 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.
2.12
This module is 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, host manufacturer have to consult with module manufacturer
for the installation method in end system.
