Daily Maintenance
Do not install or place the machine near a heat source, or place it in direct sunlight, in a
dusty or humid environment, or where there is mechanical vibration or shock. To ensure
performance, keep it away from high voltage, transmission grid, large metal objects,
radar stations and other equipment.
Do not wipe the body with chemical agents, as the chemicals may cause the cover to
deteriorate or cause damage to the surface paint. If there is dust or dirt, turn off the
power and wipe it with a soft cloth. Wipe the touch screen gently with a clean soft
cloth.
Do not switch the machine on and off frequently, as this will affect the machine’s
service life. After a normal shutdown, please wait at least three minutes before turning
it back on. If it is not to be used for a long period of time, please turn off the power and
unplug the power cord.
Do not set the brightness and contrast to the maximum value for extended periods of
time as this affects the service life of the screen.
Do not write on the touch screen with any hard object in order to avoid scratching.
Infrared Strip Cleaning
The machine utilizes an infrared matrix in the horizontal and vertical directions to detect and
locate the user’s touch. There are infrared strips (i.e., IR receiving tubes and IR transmitting
tubes) around the screen, which form an optical net made of infrared rays on the surface of
the screen. When you touch the screen, fingers or other opaque objects will block the
horizontal and vertical infrared rays that pass through the point, and the controller will
determine the coordinate position of the point.
Due to the long-term exposure to the air, the surface of the screen is extremely easy to
accumulate dust, resulting in insensitive touch or inaccurate positioning. Therefore, the
infrared strips around the screen should be cleaned regularly.
