Maintenance tips:
• Turn off the computer before cleaning the touch screen.
• Use a dry, soft, and lint-free cloth or a piece of absorbent cotton to remove fingerprints or dust from the
touch screen. Do not apply solvents to the cloth.
• The touch screen is a glass panel covered with a plastic film. Do not apply pressure or place any metallic
object on the screen, which might damage the touch panel or cause it to malfunction.
• Do not use fingernails, gloved fingers, or inanimate objects for input on the screen.
• Regularly calibrate the accuracy of the finger input to avoid a discrepancy.
