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 screen with any chemical reagent. Solvents may damage the
enclosure or paint. If the screen is stained by dust, cut off the power and then clean the
screen using a dried cloth with a little of warm water. Use a clean soft cloth to clean the
LED of the screen.
Do not frequently switch on and off the product, which may shorten the product service
life. After the screen 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 touch screen, which may scratch the LED.
The interactive touch screen 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.
