Handling the Touchscreen
Handling the Stylus
Use the stylus included with the computer. Do not use an implement other than the stylus
that comes with the computer.
Do not place any object on the surface or press down forcefully with sharp-pointed objects
(e.g., nails), or hard objects that can leave marks (e.g., pencils and ball point pens).
Do not operate the computer when such things as dust are on the screen. Do not allow
contact with substances that could dirty the touchscreen, such as oil.
When the touchscreen becomes dirty:
• Wipe to remove dirt by using a dry soft cloth included with the computer.
• Do not use benzene or thinner, or rubbing alcohol.
• For more information, refer to "Suggestions About Cleaning the LCD Surface" that
comes with the soft cloth.
Clean the stylus tip and screen prior to operation. Foreign particles can scratch the screen
and impede the operation of the stylus.
Use the stylus only for the computer screen. Using it for any other purpose may damage
the stylus and scratch the screen.
Do not use pencils, implements with sharp tips or hard objects for screen operations. The
screen may be damaged as a result.
