is installed other than notebook computers, at least 20 cm separation distance shall be maintained
between the transmitting antenna(s) to the body of user or nearby person.

2.4 Limited module procedures

The module is an unrestricted module

2.5 Trace antenna designs

The antenna(s) used for this transmitter must not be collocated or operating in conjunction with any
other antenna or transmitter within a host device, except in accordance with FCC multi-transmitter
product procedures.

2.7 Antennas

The module grantee is responsible for providing the documentation to the system integrator on
restrictions of use, for continuing compliance of the module including the maximum antenna gain
(6dBi), minimum antenna gain (3dBi), Antenna connector is a unique I-PEX connector.

2.8 Label and compliance information

The regulatory label on the final system must include the statement:

Contains FCC

ID:Z4T

-WM7628N-A

using electronic labeling method as documented in KDB 784748.

2.9 Information on test modes and additional testing requirements

OEM manufacturer should perform additional verification/validation on supported modes and is
responsible for validation testing of  host.
The final system integrator must ensure there is no instruction provided in the user manual or
customer documentation indicating how to install or remove the transmitter module except such
device has implemented two-ways authentication between moduleand the host system.

2.10 Additional testing, Part 15 Subpart B disclaimer

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.
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.
7. It is forbidden to operate transmitters outside the 2.4-2.4835 GHz frequency band to control or
communicate
8. The certified WLAN module will be installed in mobile application.
9.This module is for integration into a host system which is intended.
