Touchscreen monitor
Control a PC by tapping the screen instead of using an input device such as a keyboard or
mouse. The touch screen functions by detecting a minute electric current that runs through
your body (capacitive). Make sure to use the surface of your finger tip when tapping the screen.
Read below before using the product
• Take extra care to ensure an electrical substance does not contact the screen. The screen
may not function properly if there is static.
• Do not press hard on the touchscreen with your finger tip. Do not use a sharp object when
tapping the screen. The screen may break or get damaged.
• Do not tap the screen while wearing a glove, with a dirty finger, or using something sharp
such as your fingernail or a ballpoint pen. The screen may not function properly.
• Take extra care to ensure the screen does not contact moisture. The touch sensor may not
function properly.
• Displaying a still image on the screen for an extended period of time may cause after
images (screen degradation) or stains. Switch off the screen when not in use.
