Maintenance Tips
•
Do not put or install the product near a heat source or under direct sunlight, or in dusty or humid
places, or somewhere the product may be hit or damaged by mechanical vibration. To maximize
the 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 reagent. 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 of warm water. Use a clean soft cloth to clean the LED of the display.
•
Do not frequently switch on and off the product, which may shorten the product service life. After
the display is switched off, wait for three minutes before switching it on again. If the product is
not to be used for a long 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 a long period of time, which may
shorten the LED service life.
•
Do not use a hard object to write on the display, which may scratch the LED.
Clean the Infrared Tube
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 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.
