❖ To remain in conformance with European spectrum usage laws for

Wireless LAN operation, the above 2.4 GHz and 5 GHz channel
limitations apply. The user should use the wireless LAN utility to
check the current channel of operation. If operation is occurring
outside of the allowable frequencies as listed above, the user must
cease operating the Wireless LAN at that location and consult the
local technical support staff responsible for the wireless network.

❖ The 5 GHz Turbo mode feature is not allowed for operation in any

European Community country.

❖ This device must not be operated in ad-hoc mode using channels in

the 5 GHz bands in the European Community. Ad-hoc mode provides

a direct communication between two client devices without a Wireless
LAN Access Point.

❖ This device must be used with Access Points that have employed and

activated a radar detection feature required for European Community
operation in the 5 GHz bands. This device will operate under the
control of the Access Point in order to avoid operating on a channel
occupied by any radar system in the area. The presence of nearby
radar operation may result in temporary interruption of operation of
this device. The Access Point’s radar detection feature will
automatically restart operation on a channel free of radar. You may
consult with the local technical support staff responsible for the
wireless network to ensure the Access Point device(s) are properly
configured for European Community operation.

Bluetooth® Wireless Technology Interoperability

Bluetooth® Cards from TOSHIBA are designed to be interoperable with

any product with Bluetooth wireless technology that is based on Frequency
Hopping Spread Spectrum (FHSS) radio technology, and is compliant to:

❖ Bluetooth Specification as defined and approved by The Bluetooth

Special Interest Group.

❖ Logo certification with Bluetooth wireless technology as defined by

The Bluetooth Special Interest Group.

Bluetooth wireless technology is a new innovative technology, and TOSHIBA has
not confirmed compatibility of its Bluetooth products with all computers and/or
equipment using Bluetooth wireless technology other than TOSHIBA portable
computers.

Always use Bluetooth cards from TOSHIBA in order to enable wireless networks
over two or more (up to a total of seven) TOSHIBA portable computers using these
cards. Please contact TOSHIBA computer product support on Web site
http://www.toshiba-europe.com/computers/tnt/bluetooth.htm in Europe or
pcsupport.toshiba.com in the United States for more information.

When you use Bluetooth cards from TOSHIBA close to 2.4 GHz Wireless
LAN devices, Bluetooth transmissions might slow down or cause errors. If
you detect certain interference while you use Bluetooth cards from
TOSHIBA, always change the frequency, move your computer to the area
outside of the interference range of 2.4 GHz Wireless LAN devices
(40 meters/43.74 yards or more) or stop transmitting from your computer.
Please contact TOSHIBA computer product support on Web site
http://www.toshiba-europe.com/computers/tnt/bluetooth.htm in Europe or
pcsupport.toshiba.com in the United States for more information.

Bluetooth and Wireless LAN devices operate within the same radio
frequency range and may interfere with one another. If you use Bluetooth
and Wireless LAN devices simultaneously, you may occasionally
experience a less than optimal network performance or even lose your
network connection. If you should experience any such problem,
immediately turn off either one of your Bluetooth or Wireless LAN.
Please contact Toshiba computer product support on Web site

Bluetooth® Wireless Technology and Your Health

The products with Bluetooth® wireless technology, like other radio devices,
emit radio frequency electromagnetic energy. The level of energy emitted
by devices with Bluetooth wireless technology however is much less than
the electromagnetic energy emitted by wireless devices such as mobile
phones.

Because products with Bluetooth wireless technology operate within the
guidelines found in radio frequency safety standards and recommendations,
TOSHIBA believes Bluetooth wireless technology is safe for use by
consumers. These standards and recommendations reflect the consensus of
the scientific community and result from deliberations of panels and
committees of scientists who continually review and interpret the extensive
research literature.

In some situations or environments, the use of Bluetooth wireless
technology may be restricted by the proprietor of the building or
responsible representatives of the organization. These situations may for
example include:

14

❖ Using the equipment with Bluetooth wireless technology on board

airplanes, or

❖ In any other environment where the risk of interference to other

devices or services is perceived or identified as harmful.

If you are uncertain of the policy that applies on the use of wireless devices
in a specific organization or environment (e.g. airports), you are
encouraged to ask for authorization to use the device with Bluetooth
wireless technology prior to turning on the equipment.

Exposure to Radio Frequency Radiation
The radiated output power of the Bluetooth Card from TOSHIBA is far below

the FCC radio frequency exposure limits. Nevertheless, the Bluetooth Card
from TOSHIBA shall be used in such a manner that the potential for human
contact during normal operation is minimized.

Regulatory statements

This product complies with any mandatory product specification in any
country/region where the product is sold. In addition, the product complies
with the following:

European Union (EU) and EFTA

This equipment complies with the R&TTE directive 1999/5/EC and has
