Cleaning
The screen brightness may decrease if dust or another foreign material is adhering to the surface of the pixel
card.
The magnet used to install the pixel cards also attracts magnetic metal particles, such as iron powder.
Therefore, magnetic metal particles may adhere to areas near the magnet of the pixel card and the brightness
homogeneity of the screen may decrease.
Cleaning should be performed regularly depending on the installation environment.
Required tools (example).
(animal hair brush to prevent static electricity)
Air blower (compressor)
Cleaning method
a) Turn the LED displays off.
b) Use the soft brush to remove any dirt on the surface of the pixel card. If these parts are very dirty, use
the air blower to remove the dirt.
c) Use the soft cloth to remove the dirt on the screen surface.
d) Repeat the steps (b) and (c) to remove all the dirt.
CAUTION
• Do not use water or any other liquid.
• Do not use a stiff brush.
• Pay attention not to damage the surface of the pixel card when using the soft brush, the air blower, or the
soft cloth.
