About the LED lamps
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.
The LED lamps may absorb and hold moisture during the LED module 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
Congure the brightness settings as shown below with a video displayed on the LED module.
After a break-in period of approximately 3 hours, the LED module can be used under normal
conditions.

Installation Example
1. Installation location
Before the installation, be sure to review the following safety precautions to ensure proper and safe
installation.
CAUTION
• Ask a technician to perform the installation.
• Make sure the product is moved and installed by enough people to ensure safety.
• Make sure that the beams or the other structures to which the product is installed have enough strength to
support the weight of the product, and make sure that the product is securely xed.
• Do not install directly the product to a surface that has not enough strength.
• When installing the product in a narrow place (in a wall, etc.), leave gaps around the LED screens as
shown in the gure below to prevent an increase in the temperature. The gure below is only an example.
Pay particular attention to the installation environment (heat from the external environment, direct
sunlight, heat generated by the number of displays) in order to facilitate cooling of the LED modules.
If cooling is not sufcient, take measures, such as increasing the distance from the walls or installing a
forced-air cooling system.
Ask a technician or your retailer for more details.
