Recommended Use & Maintenance

About the LED lamps

The surface of the pixel card is vulnerable to shocks, so do not press or hit the surface.

LED lamps are sensitive to static electricity and surge voltage, which may damage their components and decrease their reliability.

Take measures against static electricity during the installation. Do not touch the LED display areas.

When you install the product or when you use it for the first time after leaving it unused for a long time, follow the instructions below.

The LED lamps may absorb and hold moisture during the LED display installation or if not used for a long time. Therefore, in such cases, the brightness must be increased gradually during a break-in period before setting the normal brightness.

If the LED lamps are lit with 100% brightness while moisture is retained, the temperature will rise very quickly and the water inside the lamps will evaporate and expand. This will cause the encapsulating resin to expand, which may lead to separation of the boundary surface inside the LED lamps. This separation can cause the LED lamps not to light up properly.

Lamp break-in

Configure the brightness settings as shown below with a video displayed on the LED display.

After a break-in period of approximately 3 hours, the LED display can be used under normal conditions.

About the Pixel card

The surface of the pixel card is easily scratched, so handle it with care so as not to push or rub it with a hard object. Be careful not to stain the surface of the pixel card with your fingers. If the surface of the pixel card becomes dirty, wipe it gently with a dry cloth. Also, use a clean cloth and avoid using the same cloth repeatedly.

What can be done with Auto Upload Module

When "Auto Upload Module" is set, if the power of the LED display is restarted after the pixel card replacement, the calibration data of all pixel cards in the display, including the pixel card that has been replaced, is automatically written to the receiving card, and the image is displayed according to this state.

Precautions related to the operation (Adjusting the colors on a part of the screen)

Set "Auto Upload Module" to off when performing "Adjusting the colors on a part of the screen". (Uncheck "Auto Upload Module" and click "Save to HW".)

Since the calibration data adjusted with "Adjusting the colors on a part of the screen" is saved in the receiving card and used for the display, if "Auto Upload Module" is checked, the calibration data in all the pixels cards inside the display whose pixel card has been replaced is written to the receiving card when the power is turned on and the results of the adjustment performed with "Adjusting the colors on a part of the screen" is lost. Then, the calibration data in the pixel card is used to display the image.

Detailed procedure

To set Auto Update Module, it is necessary to set module IDs to each pixel card and to register these module IDs to the receiving card.

Once module IDs are set to the pixel cards, registration of the module IDs to the receiving card is performed with Module Flash.
