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.
Stress injury
Carefully read the Instruction Manual for Safety and Comfort. It contains
information on 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 work space design, posture and lighting that can
help reduce physical stress.
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 (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.
