Caution: To comply with FCC RF exposure compliance
requirements, a separation distance of at least 20 cm (8 inches)
must be maintained between the antenna for the integrated
wireless LAN Mini PCI Card built in to the screen section and all
persons.
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 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.
