Information for Wireless Devices
Wireless Technology Interoperability
The Wireless LAN is compatible with other LAN systems Direct Sequence
Spread Spectrum (DSSS) /Orthogonal Frequency Division Multiplexing (OFDM) radio technology, and is compliant to:
The IEEE 802.11 Standard on Wireless LANs (Revision a/b/g/n, b/g/n
or Revision a/b/g/n/ac), as defined and approved by the Institute of
Electrical and Electronics Engineers.
Bluetooth ®
 Modules 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 (depending on the model you purchased), as
defined and approved by the Bluetooth Special Interest Group.
Logo certification with Bluetooth wireless technology as defined by the Bluetooth Special interest Group.
This Bluetooth product is not compatible with devices using Bluetooth
Version 1.0B specifications.
User's Manual 7-3       
						

							The wireless devices have not completed verification of connection andoperation with all devices which are using the Wireless LAN or Bluetoothradio technology.
Bluetooth and Wireless LAN devices operate within the same radio
frequency range and might interfere with one another. If you use Bluetooth
and Wireless LAN devices simultaneously, you might occasionally experience a less than optimal network performance or even lose yournetwork connection.
If you experience any such problem, immediately turn off either one of your
Bluetooth or Wireless LAN.

Wireless Devices and your health
Wireless products, like other radio devices, emit radio frequencyelectromagnetic energy. The level of energy emitted by Wireless products
however is far much less than the electromagnetic energy emitted by
wireless devices like for example mobile phones.
Because Wireless products operate within the guidelines found in radio
frequency safety standards and recommendations, TOSHIBA believes that
Wireless products are 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 Wireless products might be
restricted by the proprietor of the building or responsible representatives of
the organization. These situations might for example include:
Using the Wireless products equipment on board of 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 (for example, airports), you are encouraged to ask for authorization to use the Wireless device prior to
turning on the equipment.
Wireless LAN Technology The wireless communication function of the computer supports somewireless communication devices.
User's Manual 7-4 
						

							Only some models are equipped with both Wireless LAN and Bluetoothfunctions.Do not use the Wireless LAN (Wi-Fi) or Bluetooth functionalities near a
microwave oven or in areas subject to radio interference or magnetic fields. Interference from a microwave oven or other source can disruptWi-Fi or Bluetooth operation.
Turn off all wireless functionalities when near a person who mighthave a cardiac pacemaker implant or other medical electric device.Radio waves might affect pacemaker or medical device operation,
possibly resulting in serious injury. Follow the instruction for your medical device when using any wireless functionality.
Always turn off wireless functionality if the computer is near automaticcontrol equipment or appliances such as automatic doors or firedetectors. Radio waves can cause malfunction of such equipment,
possibly resulting in serious injury.
It might not be possible to make a network connection to a specified network name using the ad hoc network function. If this occurs, thenew network (*) has to be configured for all computers connected to
the same network in order to re-enable network connections.
* Make sure to use new network name.
Security
TOSHIBA strongly recommends that you enable encryption
functionality, otherwise your computer is open to illegal access by an outsider using a wireless connection. If this occurs, the outsider might
illegally access your system, eavesdrop, or cause the loss or destruction of stored data.
TOSHIBA is not liable for the loss of data due to eavesdropping or
illegal access through the wireless LAN and the damage thereof.

							Wireless communication is often subject to local radio regulations.
Although Wireless LAN wireless networking products have been designed
for operation in the license-free 2.4 GHz and 5 GHz band, local radio regulations might impose a number of limitations to the use of wirelesscommunication equipment.Radio FrequencyBand 5 GHz (5150-5850 MHz) (Revision a
and n)
Band 2.4 GHz (2400-2483.5 MHz) (Revision
b/g and n)
The range of the wireless signal is related to the transmit rate of the
wireless communication. Communications at lower transmit range might travel larger distances.
The range of your wireless devices can be affected when the
antennas are placed near metal surfaces and solid high-density materials.
Range is also impacted due to "obstacles" in the signal path of the
radio that might either absorb or reflect the radio signal.
Radio Frequency Interference Requirements
This device is restricted to indoor use due to its operation in the 5.15 to
5.25GHz frequency range.
High-power radars are allocated as primary users (i.e. priority users) of the
bands 5.25 to 5.35GHz and 5.65 to 5.85GHz and that these radars could cause interference and/or damage to LE-LAN devices.
Bluetooth wireless technology Some computers in this series have Bluetooth wireless communication
function which eliminates the need for cables between electronic devices
such as computers, printers, and mobile phones. When it is enabled,
Bluetooth provides the wireless personal area network environment which
is safe and trustworthy, that is quick and easy.
You cannot use the built-in Bluetooth functions of the computer and an external Bluetooth adaptor simultaneously. For reference, Bluetooth wireless technology has the following features:
Security
Two advanced security mechanisms ensure a high level of security:
Authentication prevents access to critical data and makes it impossible
to falsify the origin of a message.
Encryption prevents eavesdropping and maintains link privacy.

							Worldwide operation
The Bluetooth radio transmitter and receiver operate in the 2.4 GHz band,which is license-free and compatible with radio systems in most countriesin the world.
Radio links
You can easily establish links between two or more devices, with theselinks being maintained even if the devices are not within a line-of-sight of each other.
Radio Regulatory Information The Wireless device must be installed and used in strict accordance with
the manufacturer’s instructions as described in the user documentation that
comes with the product. This product complies with the following radio
