Installing the pixel card

CAUTION
• The pixel cards contain powerful magnets. If magnetic cards come close to the pixel cards, the data
contained within may be damaged. Therefore, do not carry any magnetic card when installing the pixel
cards.
• When installing the pixel cards, pay attention not to damage them against the pixel cards already installed
or other objects. Otherwise, the video may not be displayed properly.
• Take measures against static electricity when installing the pixel card. Do not touch the LED display areas
and the back of the pixel card.
• Check that the power supply to the LED modules is cut before starting the work.
• Before installing or removing pixel cards, please ensure the wall has been powered off for 1 or 2 hours.
Otherwise the thermal expansion of pixel cards increases the risk of damaging them during removal or
insertion.
• If installation is not successful, please use the maintenance tool. (see English-55)
Install the pixel card to the cabinet paying attention that the arrows on the back of the pixel card and on the
hub board are orientated toward the same direction, and that the two guide pins of the pixel card are aligned
to the guide holes of the cabinet (two for each pixel card).
The pixel card is secured by the 14 magnets on each pixel card.
