Appendix B Usage Precautions B-1
Usage Precautions
Please do not disassemble or assemble this product by yourself in any way. Opening or
removing the cover without authorization may expose you to dangerous voltage or other
hazards. If you have any maintenance matters, please contact professional
maintenance personnel for handling.
If the unit is dirty, please unplug the unit and wipe it with a soft semi-dry cloth dipped in
a small amount of water, do not repeatedly wipe the display to avoid scratches. Do not
use alcohol, gasoline, acid, alkali, detergent, volatile oil, thinner and other solvents to
wipe the machine. These solvents may cause material deterioration or damage the
paint surface.
Under the environment of high humidity, there may be water mist inside the screen,
which is normal. This is due to the reason of weather humidity and temperature caused
by the difference in temperature between the outer glass and the inner glass surface to
produce condensation in the glass inner surface of the small water droplets. It will
disappear automatically after 24 hours of normal use. Please feel free to use it.
Do not put any sharp objects or metal objects into the cooling hole or touch the signal
connector to avoid damage or electric shock caused by short circuit.
The main material of the LCD screen is glass, which is fragile. Do not apply pressure to the
LCD screen to avoid damage.
Do not place the machine on an unstable trolley, shelf or table, which may cause the
machine to tip over. The machine should be moved with care when placed on a cart. A
quick and sudden stop, too much force or uneven ground can cause carts and machines
to tip over.
The openings on the machine are designed for ventilation and heat dissipation to
ensure the reliable operation of the components in the machine and prevent
overheating. Ventilation should not be impeded by covering such items as
newspapers, tablecloths and curtains.
Do not let the machine for a long time to display the same picture or the active picture
contains a long time fixed text, icons, etc., this will leave "residual shadow" on the
screen, and does not disappear in a long period of time after shutdown the machine.
