Clean The Infrared Tube - Genee World G-Touch T15 Classic User Manual

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.
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.
