Notices
Federal Communications Commission Statement
This device complies with Part 15 of the FCC Rules. Operation is subject to the
following two conditions:
• This device may not cause harmful interference, and
• This device must accept any interference received including interference that
may 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 and, if not installed and used in accordance with manufacturer’s
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 to 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.
The use of shielded cables for connection of the monitor to the graphics card is
required to assure compliance with FCC regulations. Changes or modications
to this unit not expressly approved by the party responsible for compliance
could void the user’s authority to operate this equipment.
FCC Radio Frequency (RF) Exposure Caution Statement
Any changes or modications not expressly approved by the party responsible
for compliance could void the user’s authority to operate this equipment. “The
manufacture declares that this device is limited to Channels 1 through 11 in the
2.4GHz frequency by specied rmware controlled in the USA.”
This equipment complies with FCC radiation exposure limits set forth for an
uncontrolled environment. To maintain compliance with FCC RF exposure
compliance requirements, please avoid direct contact to the transmitting antenna
during transmitting. End users must follow the specic operating instructions for
satisfying RF exposure compliance.

viii
RF exposure warning
This equipment must be installed and operated in accordance with provided
instructions and the antenna(s) used for this transmitter must be installed to
provide a separation distance of at least 20 cm from all persons and must not
be co-located or operating in conjunction with any other antenna or transmitter.
End-users and installers must be provide with antenna installation instructions and
transmitter operating conditions for satisfying RF exposure compliance.

Wireless Operation Channel for Different Domains
N. America 2.412-2.462 GHz Ch01 through CH11
Japan 2.412-2.484 GHz Ch01 through Ch14
Europe ETSI 2.412-2.472 GHz Ch01 through Ch13
France Restricted Wireless Frequency Bands
Some areas of France have a restricted frequency band. The worst case maximum
authorized power indoors are:
• 10mW for the entire 2.4 GHz band (2400 MHz–2483.5 MHz)
• 100mW for frequencies between 2446.5 MHz and 2483.5 MHz
Channels 10 through 13 inclusive operate in the band 2446.6 MHz to 2483.5
MHz.
There are few possibilities for outdoor use: On private property or on the private
property of public persons, use is subject to a preliminary authorization procedure
by the Ministry of Defense, with maximum authorized power of 100mW in the
2446.5–2483.5 MHz band. Use outdoors on public property is not permitted.
In the departments listed below, for the entire 2.4 GHz band:
• Maximum authorized power indoors is 100mW
• Maximum authorized power outdoors is 10mW
Departments in which the use of the 2400–2483.5 MHz band is permitted with an
EIRP of less than 100mW indoors and less than 10mW outdoors:
01 Ain 02 Aisne 03 Allier 05 Hautes Alpes
08 Ardennes 09 Ariège 11 Aude 12 Aveyron
16 Charente 24 Dordogne 25 Doubs 26 Drôme
32 Gers 36 Indre 37 Indre et Loire 41 Loir et Cher

94 Val de Marne
This requirement is likely to change over time, allowing you to use your wireless
LAN card in more areas within France. Please check with ART for the latest
information (www.arcep.fr)
Your WLAN Card transmits less than 100mW, but more than 10mW.
