4 Warning:
Warning: changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority
to operate the equipment.
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.
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.
RF Exposure:
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.
Module statement:
Labelling Instruction for Host Product Integrator 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 the following: “Contains FCC ID:
2AOKI-WFR710RTU1” any similar wording that expresses the same meaning may be used.
Installation Notice to Host Product Manufacturer 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.
Antenna Change Notice to Host manufacturer If you desire to increase antenna gain and either change antenna type or use same
antenna type certified, a Class II permissive change application is required to be filed by us, or you (host manufacturer) can take
responsibility through the change in FCC ID (new application) procedure followed by a Class II permissive change application.
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.

This device is intended only for host manufacturers under the following conditions:
The transmitter module may not be co-located with any other transmitter or antenna;
The module shall be only used with the internal antenna(s) that has been originally tested and certified with this module. The
antenna must be either permanently attached or employa ‘unique’ antenna coupler.
As long as the conditions above are met, further transmitter test will not be required. However, the host manufacturer is still
responsible for testing their end-product for any additional compliance requirements required with this module installed (for
example, digital device emissions, PC peripheral requirements, etc.).
7）Label and compliance information
Host product manufacturers need to provide a physical or e-label stating “Contains FCC ID: 2AOKI-WFR710RTU1” with their
finished product.
