FCC Radiation Exposure Statement

CAUTION:

• The radiated output power of WiFi Module 802.11bgn devices is far below the FCC radio

frequency exposure limits. Nevertheless, WiFi Module 802.11bgn devices should be used in such

a manner that the potential for human contact during normal operation is minimized. To avoid

the possibility of exceeding the FCC radio frequency exposure limits, you should keep a distance

of at least 20 cm between you (or any other person in the vicinity) and the antenna.

Interference Statement

These devices comply with Part 15 of the FCC Rules. Operation of the devices is subject to the following two

conditions: (1) The devices may not cause harmful interference, and (2) The devices must accept any

interference that might cause undesired operation.

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. If the equipment is not installed and used in accordance with the instructions, the equipment might

cause harmful interference to radio communications. There is no guarantee, however, that such 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 taking one or more of the following measures:

• Relocate this device.

• Increase the separation between the device and the receiver.

• Connect the device into an outlet on a circuit different from that of other electronics.

• Consult the dealer or an experienced radio technician for help.

Modification warning statement

Changes or modifications not expressly approved by the party responsible for compliance could void the

user's authority to operate the equipment.

The end product will be labeled as “Contains Transmitter Module with FCC ID: X8UWN8020A” or

“Contains FCC ID: X8UWN8020A.”
