Clean the Infrared Tube
The interactive panel uses the horizontal and vertical infrared matrix to detect and locate the
user's touch. The screen is surrounded by an infrared tube (including the infrared acceptor and
emitter), which forms an infrared net covering on the screen surface. When a user touches the
screen, fingers or other opaque objects block the infrared rays that cross the touch point,
which helps the controller detect the coordinate position of the touch point.

which helps the controller detect the coordinate position of the touch point.
Dust is easily retained on the screen surface due to its long-term exposure in the air and
causes ineffective touch or inaccurate positioning. Therefore, you need to clean the infrared
tube around the screen regularly.
