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 anelectric 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.
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.
