    Do not use or store LED billboard in the circumstances of high temperature, high humidity and high corrosion.

    If ambient temperature is too high and may affect the normal heat dissipation, do not use the display for long time.

    Prevent any leak or other metal particles into cabinet. Dust and metal particle will affect the stability of electronic components. If leakage problem occurred, don’t use the LED billboard until it is maintained and get dry inside.

  • Tips 3: Power control

    LED module takes DC 5V power supply, NO AC accepted. When connecting the anode and cathode of the power terminal, it has to be done correctly. Otherwise, it will burn the module and even catch fire.

    Any abnormal phenomenon happens like short circuit, switch trip, wire burning or smoke etc, stop any testing when display is still powering on.

    In the environment of high humidity, LED billboard can’t be shut down for long time. If it is powered off for more than 3 days, preheating has to be performed for next use: preheat the display for 4-8 hours with 30%-50% of the full brightness to discharge the humidity inside cabinet. Then adjust to normal brightness (80%-100%). If the LED billboard is shut down for more than 7 days, then preheating should be at least 12 hours (30%-50% of full brightness).
