CON0 and CON1 are IPEX1 connectors on top side
P1 is 2*10 pins 1.27mm male header on bottom side for signals
P2 is 2*14 pins 1.27mm male header on bottom side for signals
Footprint of P1, P2 is as following, the coordinate of pin1 footprint center for P1 and P2 are
(29.5, 10.975) and (9.575,1.425), Please note that this coordinate is the center of pad, not

H1, H2, H3, H4 are slot holes used for install metal shielding cover if needed
D1 is diameter 2.1mm hole for screw fixing
D2 is diameter 2.1mm half hole for screw fixing
P3 is a 2 pins dip type header holes with 1.27mm pitch. Since P1 and P2 are all located on
lower side, this socket can be used optionally to mount module on base PCB for balancing
the force of upper side.

Federal Communication Commission Interference Statement
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 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 Caution: To assure continued compliance, any changes or modifications
not expressly approved by the party responsible for compliance could void the
user's authority to operate this equipment. (Example - use only shielded
interface cables when connecting to computer or peripheral devices).
End Product Labeling
This transmitter module is authorized only for use in devices 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 visible area with
the following: “Contains FCC ID: WHD-ORFM-WMT7620”
”
End Product Manual Information
The user manual for end users must include the following information in a
prominent location “IMPORTANT NOTE: To comply with FCC RF exposure
compliance requirements, the antenna used for this transmitter must be
installed to provide a separation distance of at least 20cm from all persons and
must not be colocated or operating in conjunction with any other antenna or
transmitter.”
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:
In the event that these conditions can not 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 can
not be used on the final product. In these circumstances, the OEM integrator
will be responsible for reevaluating the end product (including the transmitter)
and obtaining a separate FCC authorization.
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. As long as a
condition above is 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 (for
example, digital device emissions, PC peripheral requirements, etc.).
