• The RF module limited to OEM installation ONLY.
The OEM integrator is responsible for the compliance to all the rules that apply to the
product in to which this certified RF module is integrated.
• This module must be integrated into a device where the user cannot access the antenna
connector and should not be able to remove or install the module.
Dipole antenna(Under 6.15 ㏈i) can be used with this module. The antenna gain must
not exceed it.
• 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.
• 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.
- l Connect the equipment into an outlet on a circuit different from that to which the receiver
is connected.
- l Consult the dealer or an experienced radio/TV technician for help.
• FCC Caution
Any changes or modifications not expressly approved by the party responsible for compliance
could void the user's authority to operate this equipment. This transmitter must not be co-
located or operating in conjunction with any other antenna or transmitter.
• 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.
• This device is intended only for OEM integrators under the following conditions:
The antenna must be installed such that 20 cm is maintained between the antenna and users,
and The transmitter module may not be co-located with any other transmitter or antenna. As
long as 2 conditions above are met, further transmitter test will not be required. However, the
OEM integrator is still responsible for testing their end-product for any additional compliance
requirements required with this module installed.
• IMPORTANT NOTE:
In the event that these conditions cannot be met (for example certain laptop configurations
or colocation with another transmitter), then the FCC authorization is no longer considered
valid and the FCC ID cannot be used on the final product. In these circumstances, the OEM
integrator will be responsible for re-evaluating the end product (including the transmitter) and
obtaining a separate FCC authorization.
• End Product Labeling
This transmitter module is authorized only for use in device where the antenna may be
installed such that 20 cm may be maintained between the antenna and users. The final end
product must be labeled in a visible area with the following:
“Contains FCC ID: ZD7-WIMI300A”.
The grantee's FCC ID can be used only when all FCC compliance requirements are met.
• Manual Information To the End User
The OEM integrator has to be aware not to provide information to the end user regarding
how toinstall or remove this RF module in the user's manual of the end product which
integrates this module. The end user manual shall include all required regulatory
information/warning as show in this manual.
