Note: The wireless Mini PCI adapter implements a transmission diversity
function. The function does not emit radio frequencies simultaneously from
both antennas. One of the antennas is selected automatically or manually
(by users) to ensure good quality radiocommunication.
2 This device is restricted to indoor use due to its operation in the 5.15 to 5.25 GHz
frequency range. FCC requires this product to be used indoors for the frequency
range 5.15 to 5.25 GHz to reduce the potential for harmful interference to co-channel
Mobile Satellite systems.
3 High power radar is allocated as the primary user of the 5.25 to 5.35 GHz and 5.65 to
5.85 GHz bands. These radar stations can cause interference with and/or damage this
device.
4 An improper installation or unauthorized use may cause harmful interference to
radio communications. Also any tampering of the internal antenna will void the FCC
certification and your warranty.
Canada — Low-power license-exempt radio 
communication devices (RSS-210)
Exposure of humans to RF fields (RSS-102)
The notebook PC series employs low gain integral antennas that do not emit RF field in
excess of Health Canada limits for the general population; consult Safety Code 6,
obtainable from Health Canada's website at www.hc-sc.gc.ca/rpb.
This device complies with RSS210 of Industry Canada.
This Class B digital apparatus complies with Canadian ICES-003, Issue 4, and RSS-210, No 4
(Dec 2000) and No 5 (Nov 2001).
Cet appareil numérique de la classe B est conforme à la norme NMB-003, No. 4, et CNR-210,
No 4 (Dec 2000) et No 5 (Nov 2001).
"To prevent radio interference to the licensed service, this device is intended to be
operated indoors and away from windows to provide maximum shielding. Equipment (or
its transmit antenna) that is installed outdoors is subject to licensing."
« Pour empêcher que cet appareil cause du brouillage au service faisant l'objet d'une
licence, il doit être utilisé a l'intérieur et devrait être placé loin des fenêtres afin de fournir
un écran de blindage maximal. Si le matériel (ou son antenne d'émission) est installé à
l'extérieur, il doit faire l'objet d'une licence.
Caution: When using IEEE 802.11a wireless LAN, this product is restricted to indoor use due
to its operation in the 5.15- to 5.25-GHz frequency range. Industry Canada requires this
product to be used indoors for the frequency range of 5.15 GHz to 5.25 GHz to reduce the
potential for harmful interference to co-channel mobile satellite systems. High power radar
is allocated as the primary user of the 5.25- to 5.35-GHz and 5.65 to 5.85-GHz bands. These
radar stations can cause interference with and/or damage to this device.
The maximum allowed antenna gain for use with this device is 6dBi in order to comply with
the E.I.R.P limit for the 5.25- to 5.35 and 5.725 to 5.85 GHz frequency range in point-to-
point operation.
