FCC STATEMENT :
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.
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.
FCC 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.

FCC INFORMATION (additional)
OEM INTEGRATION INSTRUCTIONS:
This device is intended only for OEM integrators under the following conditions: The module must
be installed in the host equipment 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. The
module shall be only used with the internal antenna(s) that has been originally tested and
certified with this module. As long as 3 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 (for example, digital
device emissions, PC peripheral requirements, etc.).
Validity of using the module certification:
In the event that these conditions cannot be met (for example certain laptop configurations or colocation with another transmitter), then the FCC authorization for this module in combination with
the host equipment is no longer considered valid and the FCC ID of the module cannot be used
on the final product. In these circumstances, the OEM integrator will be responsible for reevaluating the end product (includin g 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: 2ACSVHF-LPT120A”.
Information that must be placed in the end user manual:
The OEM integrator has to be aware not to provide information to the end user regarding how to
install 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.
This device mustbe kept away from all persons by 20cm or more and installations using less
distance, or installations using antennas with gain greater than that with which this was Certified will
require additional approvals.
