Cleaning the touch sensors
The display uses infrared (IR) transmitters and sensors around the display’s perimeter between the
screen and the frame. Dust buildup on the protective plastic can impair touch performance. Inspect
these areas for dust and clean them every week.
CAUTION
l
Do not use compressed air to clean the sensors or borders.
l
Do not use water or cleaning agents to clean the touch sensors.
l
Do not apply too much pressure when cleaning the display because you can damage the
plastic.
To clean the IR transmitters and sensors
1. With a clean lint-free, non-abrasive cloth, gently wipe the plastic between the screen and the
frame around the perimeter of the display’s screen.
2. If dirt still remains, use 50% isopropyl alcohol (IPS) to clean the protective plastic between the
screen and the frame.
