RF Exposure compliance statement
This Module 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 and your body. This transmitter must not be co-located or operating in conjunction with any other antenna or transmitter.
Labelling Instruction for Host Product Integrator
Please notice that if the FCC and IC 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. For FCC, this exterior label should follow “Contains FCC ID: 2A9F9HL3216SE”. In accordance with FCC KDB
guidance 784748 Labeling Guidelines.
§ 15.19 Labelling requirements shall be complied on end user device.
Labelling rules for special device, please refer to §2.925, § 15.19 (a)(5) and relevant KDB publications. For E-label, please refer to §2.935.
#Information on test modes and additional testing requirements
The OEM integrator is responsible for ensuring that the end-user has no manual instruction to remove or install module.
The module is limited to installation in mobile application, a separate approval is required for all other operating configurations, including portable configurations with respect to
§2.1093 and difference antenna configurations.
Host product manufacturer is ultimately responsible for testing their end-product for any additional compliance requirements required with this module installed (for example,
digital device emissions, PC peripheral requirements, additional transmitter(s) in the host, etc.).
Test software access to different test modes: Wifi Test Tool (V1.7.2)
Antenna Change Notice to Host manufacturer
The device has an integrated trace antenna.so host manufacturer can not change antenna.

#List of applicable FCC Rules
This modular transmitter complies with FCC Rules Part 15.247.
FCC other Parts, Part 15B Compliance Requirements for Host product manufacturer
This modular transmitter is only FCC authorized for the specific rule parts listed on our grant, 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.
Host manufacturer in any case shall ensure host product which is installed and operating with the module is in compliant with Part 15B requirements.
Please note that For a Class B or Class A digital device or peripheral, the instructions furnished the user manual of the end-user product shall include statement set out in §15.105
Information to the user or such similar statement and place it in a prominent location in the text of host product manual. Original texts as following:
For Class B
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.
For Class A
Note: This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to
part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference
when the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio
frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful
interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful
interference in which case the user will be required to correct the interference at his own expense.
