z Place the computer on a flat stable surface. Do not place the computer upright. If the computer is exposed to an
extremely strong impact, it may become inoperable.
z Temperature: Operation: 5 °C to 35 °C {41 °F to 95 °F}
Storage: -20 °C to 60 °C {- 4 °F to 140 °F}
Humidity: Operation: 30% to 80% RH (No condensation)
Storage: 30% to 90% RH (No condensation)
Even within the above temperature/humidity ranges, using for a long time in an extreme environment will result in
the product deterioration and will shorten the product life.
• Be sure to use the computer in an environment with sufficient heat ventilation.
- Avoid using the computer on a highly heat retentive surfaces (e.g., rubber pads and blankets). If possible, use
the computer on surfaces that can dissipate heat, such as a steel desk.
- Do not cover the computer with towels, keyboard covers, etc., as this prevents heat dissipation.
- When using the computer, always keep the display open. (Note, however, that closing the display while the com-
puter is in use does not cause generation of heat, ignition, or other malfunctions.)
z Do not place the computer in the following areas, otherwise the computer may be damaged.
• Near electronic equipment. Image distortion or noise may occur.
• Near magnets or in magnetic fields.
• In extremely high or low temperature.
z As the computer can become hot during operation, keep it away from items that are sensitive to heat.
