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-WKCT2F 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)Antenna type is a PIFA with no more than 0.3 dBi gain at BT/BLE, 2.04 dBi for 2.4 G WIFI ,4.01 dBi gain for
5G WIFI .
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 antennas 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.

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-WKCT2F”; any similar
wording that expresses the same meaning may be used.
2.9
In accordance with FCC guidance it is recommended that the host product manufacturer perform investigative
measurements to confirm that the system does not exceed the spurious emissions limits or band edge limits
once the module is installed in the host system.
If the host system contains other transmitters additional testing is required to check for emissions that may occur
due to the intermixing of emissions with the other transmitters, digital circuitry, or due to the physical properties
of the host product (enclosure). RF exposure assessments to account for transmissions across all transmitters
that can operate simultaneously is also required.
For additional information refer to FCC KDB 996369 D04 Module Integration Guide.
2.10
The host product manufacturer is responsible for compliance with any other FCC rules that apply to the host not
covered by the modular transmitter grant of certification.

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.
