Radio frequency wireless communication can interfere
with equipment on commercial aircraft. Current
aviation regulations require wireless devices to be
turned off while traveling in an airplane.
802.11ABGN (also known as wireless Ethernet or Wi-Fi)
and Bluetooth communication devices are examples of
devices that provide wireless communication.
•
In environments where the risk of interference to other
devices or services is harmful or perceived as harmful,
the option to use a wireless device may be restricted
or eliminated. Airports, Hospitals, and Oxygen or
flammable gas laden atmospheres are limited examples
where use of wireless devices may be restricted or
eliminated. When in environments where you are
uncertain of the sanction to use wireless devices, ask
the applicable authority for authorization prior to use or
turning on the wireless device.
•
Every country has different restrictions on the use of
wireless devices. Since your system is equipped with
a wireless device, when traveling between countries
with your system, check with the local Radio Approval
authorities prior to any move or trip for any restrictions
on the use of a wireless device in the destination
country.
The RF field strength of the wireless device or devices that may
be embedded in the notebook are well below all international
RF exposure limits as known at this time. Because the wireless
devices (which may be embedded into the notebook) emit less
energy than is allowed in radio frequency safety standards and
recommendations, manufacturer believes these devices are safe
for use. Regardless of the power levels, care should be taken to
minimize human contact during normal operation.
Some circumstances require restrictions on wireless devices.
Examples of common restrictions are listed on the next page:
