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

-- Consult the dealer or an experienced radio/TV technician for help

receiver is connected.

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 Radiation Exposure Statement

The modular can be installed or integrated in mobile or fix devices only. This modular cannot

be installed in any portable device, for example, USB dongle like transmitters is forbidden.

This modular complies with FCC RF radiation exposure limits set forth for an uncontrolled

environment. This transmitter must not be collocated or operating in conjunction with any other

antenna or transmitter.

If the FCC identification number is not visible when the module is installed inside another

device, then the outside of the device into which the module is installed must also display a

label referring to the enclosed module.

This exterior label can use wording such as the following:

“Contains Transmitter Module FCC ID:2ACOE-SKW92 Or Contains FCC ID:2ACOE-SKW92''

when the module is installed inside another device, the user manual of this device must

contain below warning statements;

1. 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.

(2) This device must accept any interference received, including interference that may cause

undesired operation.

2. Changes or modifications not expressly approved by the party responsible for compliance

could void the user's authority to operate the equipment.

The devices must be installed and used in strict accordance with the manufacturer's

instructions as described in the user documentation that comes with the product.

3. Integrator is responsible for final compliance of the end-product

> > that integrates this modular transmitter.

> > 15B Compliance on final product with integrated modular transmitter

> > 15C Evaluation of RF Parameter of the modular transmitter (e.g.

> > Fundamental, Out-of-Band Emissions)

4. Integration strictly limited to host platform (Wireless Router and similar devices)

5. This module is not shielding.
