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 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 co-

location 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 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: 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 must be 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.
