The Module is designed to comply with the FCC statement. FCC ID is 2AATL-6220HL-IF. The host system
using Module, should have label indicated it contain modular’s FCC ID: 2AATL-6220HL-IF. This radio module
must not installed to collocate and operating simultaneously with other radios in host system additional testing
and equipment authorization may be required to operating simultaneously with other radio.
The Module and its antenna must not be co-located or operating in conjunction with any other transmitter or
antenna within a host device.
The modular must be installed in the host that assign by Company name: FN-LINK TECHNOLOGY LIMITED,
Model no.: 6220HL-IF if other host types used would need further evaluation and possible C2PC if they are not
significantly similar to the one tested The WIFI Module is designed for a compact PCB design. It should be
installed and operated with host or other minimum distance of 20 centimeters between the radiator and your
body." To comply with FCC regulations limiting both maximum RF output power and human exposure to RF

Notice to OEM integrator
6220HL-IF
FN-LINK TECHNOLOGY LIMITED 18
The end user manual shall include all required regulatory information/warning as show in this manual. The
OEM integrator is responsible for testing their end-product for any additional compliance requirements required
with this module installed. If the final product contains circuits of other FCC PART 15 Subparts, the final host
product still requires Part 15 Subpart B compliance testing with the modular transmitter installed The intended
use is generally not for the general public. It is generally for industry/commercial use. The connector is within
the transmitter enclosure and can only be accessed by disassembly of the transmitter that is not normally
required, the user has no access to the connector. Installation must be controlled. Installation requires special
training.
This device complies with Part 15 of the FCC Rules.
This equipment should be installed and operated with a minimum distance of 20 cm between the radiator and
your body.
2.2
This module has been assessed against the following FCC rule parts: CFR 47 FCC Part 15 C (15.247. DTS). lt
is applicable to the modular transmitter
2.3
This radio transmitter Module 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 2.7 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 and apply for Single module approval.
2.5
Trace antenna designs: applicable.
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 ll permissive change application is required to be filed by the grantee, or the host
manufacturer can take responsibility through the change in FCC lD (new application) procedure followed by a
Class ll permissive change application.
The device must be professionally installed.
The intended use is generally not for the general public.
It is generally for industry/commercial use.
The connector is within the transmitter enclosure and can only be accessed by disassembly of the transmitter
that is not normally required.
The user has no access to the connector.
Installation must be controlled.
Installation requires special training.
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
6220HL-IF
FN-LINK TECHNOLOGY LIMITED 18
manufacturer of module will inform installer to meet with the FCC part 15.203 in the warning part.
Antenna Specification list below:
BLE/2.4G WIFI:
Antenna type: PCB Antenna
The max antenna gain (in dBi):1.58 dBi
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: 2AL6K-BLM8852BP2 ";
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. lt 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 and15.209 & 15.207, part 15B: class
B requirement, only if the test result comply with FCC part 15C: 15.247, 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, lf 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.
FCC Statement
