FCC Caution:
Any Changes or modifications not expressly approved by the party responsible for compliance could void the
user's authority to operate the equipment.
This device 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.
IMPORTANT NOTE:
NOTE: 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.
FCC Radiation Exposure Statement:
This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment .This
equipment should be installed and operated with minimum distance 20cm between the radiator& your body.
OEM/Integrators Installation Manual
List of applicable FCC rules This module has been tested and found to comply with part 15.247 and part
15.407 requirements for Modular Approval.
Summarize the specific operational use conditions This module can be applied in Smart home,
Instrumentation; Wi-Fi Remote monitoring/control;Toy field; Color LED control; Intelligent integrated
management of fire protection andsecurity; Smart card terminals, wireless POS machines, handheld devices.
The input voltage to the module should be nominally 3.3 VDC, typical value 3.3VDC and the ambient
temperature of the module should not exceed 60℃.
Limited module procedures N/A
Trace antenna designs N/A
Antennas The module of MT7975DN has two Antenna ports and the antenna gain as below:
2.4G Wi-Fi: 3.13dBi;
5G Wi-Fi: Band1: 3.62dBi, Band4: 3.52dBi.
Label and compliance information When the module is installed in the host device, the FCC ID label
must be visible through a window on the final device or it must be visible when an access panel, door or
cover is easily re‐moved. If not, a second label must be placed on the outside of the final device that contains
the following text: Contains Transmitter Module
FCC ID: 2AD56HLK-RM60, the FCC ID can be used only when all FCC ID compliance requirements are
met.
Information on test modes and additional testing requirements
a) 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).
b) The testing should check for emissions that may occur due to the intermixing of emissions with the

User Manual
- 18 -
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. It is important to note that
host product manufacturers should not assume that because the modular transmitter is certified that
they do not have any responsibility for final product compliance.
c) If the investigation indicates a compliance concern the host product manufacturer is obligated to
mitigate the issue. Host products using a modular transmitter are subject to all the applicable individual
technical rules as well as to the general conditions of operation in Sections 15.5, 15.15, and 15.29 to
not cause interference. The operator of the host product will be obligated to stop operating the device
until the interference has been corrected.
Additional testing, Part 15 Subpart B disclaimer
The final host / module combination need to be evaluated against the FCC Part 15B criteria for unintentional
radiators in order to be properly authorized for operation as a Part15 digital device. The host integrator
installing this module into their product must ensure that the final composite product complies with the FCC
requirements by a technical assessment or evaluation to the FCC rules, including the transmitter operation
and should refer to guidance in KDB 996369. For host products with certified modular transmitter, the
frequency range of investigation of the composite system is specified by rule in Sections 15.33(a)(1) through
(a)(3), or the range applicable to the digital device, as shown in Section 15.33(b)(1), whichever is the higher
frequency range of investigation. When testing the host product, all the transmitters must be operating. The
transmitters can be enabled by using publicly available drivers and turned on, so the transmitters are active. In
certain conditions it might beappropriate to use a technology-specific call box (test set) where accessory
devices or drivers are not available. When testing for emissions from the unintentional radiator, the
transmitter shall be placed in the receive mode or idle mode, if possible. If receive mode only is not possible
then, the radio shall be passive (preferred) and/or active scanning. In these cases, this would need to enable
activity on the communication BUS (i.e., PCIe, SDIO, USB) to ensure the unintentional radiator circuitry is
enabled. Testing laboratories may need to add attenuation or filters depending on the signal strength of any
active beacons (if applicable) from the enabled radio(s). See ANSI C63.4, ANSI C63.10 and ANSI C63.26
for further general testing details.
