Handling and Maintenance

Operation Environment

zPlace the computer on a flat stable surface. Do not place the computer upright or turn it over. If the computer is exposed to an extremely strong impact, it may become inoperable.

zTemperature: 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.

zDo not place the computer in the following areas, otherwise the computer may be damaged.

•Near electronic equipment. Image distortion or noise may occur.

•In extremely high or low temperature.

zAs the computer can become hot during operation, keep it away from items that are sensitive to heat.

Handling Cautions

This computer is designed to minimize shock to parts such as the LCD and the hard disk drive and equipped with a drip- proof keyboard, but no warranty is provided against any trouble caused by shock. Be extremely careful when handling the computer.

zWhen carrying the computer:

•Turn off the computer.

•Remove all external devices, cables, cards and other protruding things.
