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 panel with any chemical reagent. Solvents may damage the enclosure or
paint. If the panel is stained by dust, cut off the power and then clean the panel using a
dried cloth with a little of warm water. Use a clean soft cloth to clean the LCD of the
panel.

Do not frequently switch on and off the product, which may shorten the product service
life. After the panel 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 LCD for a long period of time, which
may shorten the LCD service life.

Do not use a hard object to write on the touch screen, which may scratch the LCD.
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.
