Icons
Icons identify ports, dials, and other parts of your computer. The indicator
panel also uses icons to identify the components it is providing information
on.
Keys
The keyboard keys are used in the text to describe many computer
operations. A distinctive typeface identifies the key top symbols as they
appear on the keyboard. For example, ENTER identifies the ENTER key.
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.

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.
Provide adequate ventilation
Always make sure your computer and AC adaptor have adequate
ventilation and are protected from overheating when the power is turned on
or when an AC adaptor is connected to a power outlet (even if your
computer is in Sleep Mode). In this condition, observe the following:
■ Never cover your computer or AC adaptor with any object.
■ Never place your computer or AC adaptor near a heat source, such as
an electric blanket or heater.
■ Never cover or block the air vents including those located at the base of
the computer.
■ Always operate your computer on a hard flat surface. Using your
computer on a carpet or other soft material can block the vents.
■ Always provide sufficient space around the computer.
■ Overheating your computer or AC adaptor could cause system failure,
computer or AC adaptor damage or a fire, possibly resulting in serious
injury.
User’s Manual xv
Creating a computer-friendly environment
Place the computer on a flat surface that is large enough for the computer
and any other items you are using, such as a printer.
Leave enough space around the computer and other equipment to provide
adequate ventilation. Otherwise, they may overheat.
To keep your computer in prime operating condition, protect your work area
from:
■ Dust, moisture, and direct sunlight.
■ Equipment that generates a strong electromagnetic field, such as
stereo speakers (other than speakers that are connected to the
computer) or speakerphones.
■ Rapid changes in temperature or humidity and sources of temperature
change such as air conditioner vents or heaters.
■ Extreme heat, cold, or humidity.
■ Liquids and corrosive chemicals.
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
that can be caused by extensive keyboard use.
General Precautions
Heat injury
■ 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, for example if you rest the
computer on your lap or if you keep your hands on the palm rest, your
skin might suffer a low-heat injury.
■ If the computer has been used for a long time, avoid direct contact with
the metal plate supporting the various interface ports as this can
become hot.
■ The surface of the AC adaptor can become hot when in use but this
condition does not indicate a malfunction. If you need to transport the
AC adaptor, you should disconnect it and let it cool before moving it.
■ Do not lay the AC adaptor on a material that is sensitive to heat as the
material could become damaged.
User’s Manual xvi
Pressure or impact damage
Do not apply heavy pressure to the computer or subject it to any form of
strong impact as this can damage the computer's components or otherwise
cause it to malfunction.
Mobile phones
Please be aware that the use of mobile phones can interfere with the audio
system. The operation of the computer will not be impaired in any way, but
it is recommended that a minimum distance of 30cm is maintained between
the computer and a mobile phone that is in use.
Instruction Manual for Safety and Comfort
All important information on the safe and proper use of this computer is
described in the enclosed Instruction Manual for Safety and Comfort. Be
sure to read it before using the computer.
