13Useful Information● Magnetic sensorThe magnetic sensor on the computer operates by detecting geomagnetism. Therefore, themagnetic sensor may not function properly and it readings may be inaccurate, especially in thefollowing environments.• Inside or near steel structures such as buildings or bridges• Inside or near automobiles, or near train power lines• Near metallic furniture or appliances• When the AC adaptor or other peripheral devices are brought closer to the computer• Near magnets, speakers, or other objects with strong magnetic fieldsThe magnetic directions indicated by the magnetic sensor may not be accurate immediately afterpurchase or in environments with poor magnetic fields.In such cases, turn on the computer and move it as follows.Hold the computer so that its screen side is facing upward and level.While keeping the computer level, rotate it 90 degrees or more clockwise.Return the computer to position , and rotate it 90 degrees or more counterclockwise.Return the computer to position .Tilt the computer 90 degrees or more to the left so that the left side of the computer tilts down.Return the computer to position , and tilt it 90 degrees or more to the right so that the rightside of the computer tilts down.CAUTION● Hold the computer firmly when moving it. Strong shocks from dropping the computer mayresult in damage.MaintenanceTo clean the LCD panelUse the soft cloth included with the computer. (For further information, refer to è ReferenceManual “Screen Input Operation” - “Suggestions About Cleaning the LCD Surface”.)To clean areas other than the LCD panelWipe with a soft dry cloth such as gauze. When using detergent, dip a soft cloth in water-diluteddetergent and wring it thoroughly.CAUTION● Do not use benzene, thinner, or rubbing alcohol since it may adversely affect the surface causingdiscoloration, etc. Do not use commercially-available household cleaners and cosmetics, as theymay contain components harmful to the surface.● Do not apply water or detergent directly to the computer, since liquid may enter inside of thecomputer and cause malfunction or damage.
