Maintenance Tips
Clean the Infrared Sensor
●
●
● Do not put or install the product near a heat source, under direct sunlight, in dusty or
humid places, or somewhere the product may be hit or damaged by mechanical
vibration. To maximize performance, it needs to be put away from equipment such as grid,
large metal objects and radar stations as far as possible.
● Do not wipe the display with any chemical agent. Solvents may damage the
enclosure or paint. If the display is stained by dust, cut off the power and then clean the
display using a dried cloth with a little warm water. Use a clean, soft cloth to clean the
LED of the display.
Do not frequently switch the product on and off. It may shorten the product service
life. After the display is switched off, wait three minutes before switching it on again. If the
product is not to be used for an extended period of time, please power off the product
and pull out the power plug.
●
Do not maximize the brightness and contrast of the LED for an extended period of
time
. It may shorten the LED service life.
Do not use a hard object to write on the display, which may scratch the LED.
The interactive display uses the horizontal and vertical infrared matrix to detect and
locate the user's touch. The screen is surrounded by an infrared sensor (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 sensors
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 sensors around the screen regularly.
