with your monitor for further information.ProblemProcedureMonitor does not
turn onAfter confirming that the monitor's power switch is
on, you should check the connections to make
sure that the power cord/adaptor is firmly
connected to the monitor and to a working power outlet.No displayTry adjusting the contrast and brightness controlson the external monitor.
Press the function key in order to change the
display priority and ensure that it is not set for the
internal display only.
Check to see if the external monitor is connected.
When the external monitor is set as the primary
display device in extended desktop mode, it will not
display when the computer wakes up from Sleep
Mode if the external monitor has been
disconnected while in Sleep Mode.
To keep this from happening, do not disconnect
the external monitor while the computer is in Sleep
or Hibernation Mode.
Remember to turn off the computer before
disconnecting the external monitor.
When the display panel and an external monitor
are set to clone mode and they are turned off by
the timer, the display panel or the external monitor
may not display when turned on again.
If this occurs, press the function key to re-set the
display panel and external monitor to clone mode.Display error occursCheck that the cable connecting the external
monitor to the computer is firmly attached.

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 or b/g/
n), as defined and approved by the Institute of Electrical and
Electronics Engineers.
Bluetooth ®
 Cards 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.
The wireless devices have not completed verification of connection and
operation 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 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.User's Manual 7-4

Wireless Devices and your health
Wireless products, like other radio devices, emit radio frequencyelectromagnetic energy. The level of energy emitted by Wireless productshowever 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
Wireless products 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 Wireless products may be
restricted by the proprietor of the building or responsible representatives of the organization. These situations may 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 (e.g. airports), you are encouraged to ask for authorization to use the Wireless device prior to
turning on the equipment.
Wireless LAN Technology The computer’s wireless communication function supports some wirelesscommunication devices.
Only some models are equipped with both Wireless LAN and Bluetooth functions.
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 all wireless functionalities off when near a person who may have
a cardiac pacemaker implant or other medical electric device. Radio waves may affect pacemaker or medical device operation, possibly
resulting in serious injury. Follow the instruction for your medical
device when using any wireless functionality.
User's Manual 7-5 
						

							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 may not be possible to make a network connection to a specified network name using the ad hoc network function. If this occurs, thenew network (*) will have to be configured for all computers connected
to the same network in order to re-enable network connections.
* Please be sure to use new network name.
Security
TOSHIBA strongly recommend that you enable encryption
functionality, otherwise your computer will be open to illegal access by
an outsider using a wireless connection. If this occurs, the outsider may illegally access your system, eavesdrop, or cause the loss ordestruction 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.

Radio Characteristics
Radio Characteristics of Wireless LAN module may vary according to:
Country/region where the product was purchased
Type of product
Wireless communication is often subject to local radio regulations.
Although Wireless LAN wireless networking products have been designed
for operation in the license-free 2.4GHz and 5GHz band, local radio
regulations may impose a number of limitations to the use of wireless
communication equipment.
Radio FrequencyBand 5GHz (5150-5850 MHz) (Revision a
and n)
Band 2.4GHz (2400-2483.5 MHz) (Revision
b/g and n)
User's Manual 7-6 
						

							The range of the wireless signal is related to the transmit rate of the
wireless communication. Communications at lower transmit range may 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 may either absorb or reflect the radio signal.
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 computer's built-in Bluetooth functions 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 2.4GHz band,
which is license-free and compatible with radio systems in most countries in the world.
Radio links
You can easily establish links between two or more devices, with these links being maintained even if the devices are not within a line-of-sight ofeach other.
Radio Frequency Interference Requirements
This device is restricted to indoor use due to its operation in the 5.15 to
5.25GHz frequency range.
Radio Regulatory Information The Wireless device must be installed and used in strict accordance withthe manufacturer’s instructions as described in the user documentation that
comes with the product. This product complies with the following radio
frequency and safety standards.
