Exposure to Radio Frequency Radiation

The radiated output power of the IEEE 1394 and 802.11 internal
wireless radio is far below the FCC radio frequency exposure
limits. Nevertheless, the wireless radio shall be used in such a
manner that the potential for human contact during normal
operation is minimized.
The internal wireless radio operates within guidelines found in
radio frequency safety standards and recommendations, which
reflect the consensus of the scientific community. We therefore
believe the internal wireless radio is safe for use by consumers.
The level of energy emitted is far less than the electromagnetic
energy emitted by wireless devices such as mobile phones.
However, the use of wireless radios may be restricted in some
situations or environments, such as aboard airplanes. If you are
unsure of restrictions, you are encouraged to ask for authorization
before turning on the wireless radio.
