It is a touch screen not pressure screen. So use reasonably delicatetouch with it.• Don't use tap water or mineral water as they could leave white marks on thescreen because of the dissolved salts.• Don't use paper towels or any type of cloth that is not lint-free, as they can leaveresidue or even scratch the display.• Don't spray liquid directly on the screen. Apply liquid to a cloth and then wipe thescreen.• Don't use Windex or any other glass cleaner that contains ammonia or alcohol,as they can degrade the display panel.• Don't clean the display while it is on. When the display is dark, it is much easierto see dirt and fingerprints that need to be removed.
