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, damage to the 
computer or impaired performance. 
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 Safety 
Instruction Manual. 
Stress injury 
Carefully read the Safety Instruction Manual. It contains information on 
prevention of stress injuries to your hands and wrists that 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 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 lowheat 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. 
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 it is recommended that a distance of 30 cm 
be maintained between the computer and a mobile phone in use.
