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 injury
■
Avoid prolonged physical contact with the bottom of 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, 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.
PC Card overheating
Some PC cards can become hot with prolonged use. If two cards are
installed, both can become hot even if only one is used extensively.
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.
Pressure or impact damage
Do not apply heavy pressure to the computer or subject it to strong
impact. Excessive pressure or impact can damage computer
components or otherwise cause malfunctions.
Mobile phone
Use of mobile phones can interfere with the audio system. Computer
operation is not impaired but it is recommended that a distance of 30cm
be maintained between the computer and a mobile phone in use.
