General Precautions
TOSHIBA computers are designed to optimize safety, minimize strain and
withstand the rigors of portability. However, certain precautions should be
observed to further reduce the risk of personal injury or damage to the
computer.
Be certain to read the general precautions below and to note the cautions
included in the text of the manual. Please also refer to the Instruction
Manual for Safety and Comfort.
Stress injury
Carefully read the Instruction Manual for Safety and Comfort. It contains
information on the prevention of stress injuries to your hands and wrists
than can be caused by extensive keyboard use. Chapter 3, Getting Started,
also includes information on workspace design, posture and lighting that
can help reduce physical stress.
Heat warning
■ Avoid prolonged physical contact with the computer. If the computer is
used for long periods, its surface can become very warm. While the
temperature will not feel hot to the touch, if you maintain physical
contact with the computer for a long time (if you rest the computer on
your lap, or if you keep your hands on the palm rest, for example) your
skin might suffer low-heat injury.
■ If the computer has been used for a long time, avoid direct contact with
the metal plate supporting the I/O ports. It can become hot.
■ The surface of the AC adaptor can become hot when in use. This
condition does not indicate a malfunction. If you need to transport the
AC adaptor, disconnect it and let it cool before moving it.
■ Do not lay the AC adaptor on a material that is sensitive to heat. The
material could be damaged.
Pressure or impact damage
Do not apply heavy pressure to the computer or subject it to strong impact.
Excessive pressure or impact can cause damage to computer components
or otherwise cause malfunctions.
User’s Manual xv
PC Card overheating
Some PC Cards can become hot with prolonged use. Overheating of a
PC Card can result in errors or instability in the PC Card operation. Also be
careful when you remove a PC Card that has been used for a long time.
Mobile phones
Use of mobile phones can interfere with the audio system. Computer
operation is not impaired but is recommended that a distance of 30cm be
maintained between the computer and a mobile phone in use.
Central Processing Unit (“CPU”) Performance Disclaimer
CPU Performance in your computer product may vary from specifications
under the following conditions:
■ use of certain peripheral products
■ use of battery power instead of AC power
■ use of certain multimedia games or videos with special effects
■ use of standard telephone lines or low speed network connections
■ use of complex modeling software, such as high end computer aided
design applications
■ use of the computer in areas with low air pressure (high
altitude >1,000 meters or >3,280 feet above sea level)
■ use of the computer at temperatures outside the range of 5°C to 35°C
(41°F to 95°F) or > 25°C (77°F) at high altitude (all temperature
references are approximate)
CPU Performance may also vary from specifications due to design
configuration.
Under some conditions, your computer product may automatically
shutdown. This is a normal protective feature designed to reduce the risk of
lost data or damage to the product when used outside recommended
conditions. To avoid risk of lost data, always make back-up copies of data
by periodically storing it on an external storage medium. For optimum
performance, use your computer product only under recommended
conditions Read additional restrictions under “Environmental
Requirements” in appendix A, Specifications.

Even if your software gives no indication that any problems have occurred,
you should always check to ensure that information has been successfully
stored on recordable optical media (CD-R, CD-RW and so forth).
Wireless LAN and your Health
Wireless LAN products, like other radio devices, emit radio frequency
electromagnetic energy. The level of energy emitted by Wireless LAN
devices however is far less than the electromagnetic energy emitted by
other wireless devices such as mobile phones.
Because Wireless LAN products operate within the guidelines found in
radio frequency safety standards and recommendations, TOSHIBA
believes Wireless LAN 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 LAN may be
restricted by the proprietor of the building or responsible representatives of
the organisation. These situations may for example include:
■ Using the Wireless LAN equipment on board of aeroplanes, 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 organisation or environment (e.g. airports), you are
encouraged to ask for authorisation to use the Wireless LAN device prior to
turning on the equipment.

Abbreviations
On first appearance, and whenever necessary for clarity, abbreviations are
enclosed in parentheses following their definition. For example: Read Only
Memory (ROM). Acronyms are also defined in the Glossary.
Icons
Icons identify ports, dials, and other parts of your computer. The indicator

The keyboard keys are used in the text to describe many computer

Key operation
Some operations require you to simultaneously use two or more keys. We
identify such operations by the key top symbols separated by a plus sign
(+). For example, Ctrl + C means you must hold down Ctrl and at the same
time press C. If three keys are used, hold down the first two and at the
same time press the third.
