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 Safety Instruction Manual. 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.

General Precautions
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.
Disclaimers
LCD
Over a period of time, and depending on the usage of the computer, the
brightness of the LCD screen will deteriorate. This is an intrinsic
characteristic of LCD technology.
Maximum brightness is only available when operating in AC power mode.
Screen will dim when the computer is operated on battery power and you
may not be able to increase the brightness of the screen.
CPU
Central Processing Unit (“CPU”) Performance Disclaimer.
CPU performance in your computer product may vary from specifications
under the following conditions:
■use of certain external peripheral products
■use of battery power instead of AC power
■use of certain multimedia, computer generated graphics or video
applications
■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 several applications or functionalities simultaneously
■use of computer in area with low air pressure (high altitude >
1,000 meters or >3,280 feet above sea level)
■use of computer at temperatures outside the range of 5°C to 30°C
(41°F to 86°F) or >25°C (77°F) at high altitude (all temperature
