Operation environment
Place the computer on a fl at 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.
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.
Do 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.
As 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 han-
dling the computer.
When carrying the computer:
Turn off the computer.
Remove all external devices, cables, cards and other protruding things.
Do not drop or hit the computer against solid objects.
Do not leave the display open.
Do not grip the display part.
Do not put anything (e.g., a piece of paper) between the display and keyboard.
When you board an airplane, take the computer with you and never put it in your checked luggage. When using the
computer on airplane, follow the airline’s instructions.
When carrying a spare battery, put it in a plastic bag to protect its terminals.
The touch pad is designed to be used with a fi nger tip. Do not place any object on its surface and do not press
down strongly with sharp-pointed or hard objects that may leave marks (e.g., nails, pencils and ball point pens).
Avoid any harmful substances such as oil from getting into the touch pad. The cursor may not work correctly.
This computer contains a magnet and magnetic products at the locations circled in the
illustration at right. Avoid leaving metallic object or magnetic media in contact with these
areas.
Use only the included stylus/pen to touch the screen. Do not place any object on its sur-
face and do not press down strongly with sharp-pointed or hard objects that may leave
marks (e.g., nails, pencils and ball point pens).
Do not use the stylus/pen when dust or dirt (e.g., oil) is on the screen. Otherwise foreign
particles on the screen/stylus/pen can scratch the screen surface or obstruct the stylus/pen operation.
Use the stylus/pen only for touching the screen. Using it for any other purpose may damage the stylus/pen and
result in scratches on the screen.
<Only for model with digitizer>
The digitizer uses electromagnetic induction and may not work properly near strong electrical fi eld or magnetic fi eld
such as:
near AM radio base station or relay station antennas
near CRT displays that generate strong electromagnetic fi eld noise
Move the digitizer away from such locations so it will work properly.
The cursor cannot follow the pen movement if you move the pen too quickly.
When using peripheral devices
Follow these instructions and the Reference Manual to avoid any damage to the devices. Carefully read the instruction
manuals of the peripheral devices.
Use the peripheral devices conforming to the computer’s specifi cations.
Connect to the connectors in the correct direction.
If it is hard to insert, do not try forcibly but check the connector’s shape, direction, alignment of pins, etc.
If screws are included, fasten them securely.
Remove the cables when you carry the computer. Do not pull the cables forcibly.
