Tips on using the multi-touch screen
• The multi-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 inanimate objects, fingernails, or gloved fingers for input on the screen.
• Regularly calibrate the accuracy of the finger input to avoid a discrepancy.
Tips on cleaning the multi-touch screen
• Turn off the computer before cleaning the multi-touch screen.
• Use a dry, soft, and lint-free cloth or a piece of absorbent cotton to remove fingerprints or dust from the
multi-touch screen. Do not apply solvents to the cloth.
• Gently wipe the screen using top-down motion. Do not apply any pressure on the screen.
