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.”
