Precautions For Using Indoor LED Display Screen

1.Usage Environment:

The working environment temperature should be controlled between -20°C and 50°C, and the humidity between 10% and 90% RH. Avoid using or storing indoor LED display screens in high-temperature, high-humidity, or environments with high acid, alkali, and salt content.

2.Precautions for Turning On/Off the Screen:

When turning on the screen, first turn on the control computer, and after it is running normally, then turn on the indoor LED display screen. When turning off the screen, first turn off the power supply of the LED screen body, then close the control software and computer. Note that the time interval between turning the screen on and off should be more than 5 minutes. Avoid turning on the screen when it's a full-white screen, as this will be at maximum power and create the largest inrush current, impacting the power distribution system.

3.Power Supply Requirements:

LED modules require DC +5V power. AC power is strictly prohibited. Ensure the positive and negative terminals of the power supply are not reversed, to avoid damaging the product or causing a fire. The power supply voltage should be 220V ± 10%, frequency 50Hz ± 5%. Ensure reliable safety grounding, and that the ground wire is reliably isolated from the neutral line.

4.Moisture Prevention:

Keep conductive materials like water, iron powder, etc., strictly out of the screen body. If water enters the screen, immediately disconnect the power. Only re-energize after all components inside the screen body are completely dry.

5.Cleaning and Maintenance:

Regularly clean and maintain the indoor LED display screen to prevent dust from affecting display quality and damaging circuits. Use a soft brush to gently wipe during cleaning. Do not use any liquid substances to clean the surface of LED modules.

6.Storage Requirements:

Storage temperature requirements range from -40°C to 60°C. After opening the packaging, the indoor LED display screen must be stored in an environment where temperature <30°C and humidity <60%.

7.Avoid Frequent Power Switching:

While using the indoor LED display screen, avoid frequently switching the power. Allow at least one minute between operations to prevent excessive current, overheating of power cords, damage to LED lights, and reduced display lifespan.

8.Unauthorized Personnel Prohibited from Touching Internal Wires:

To avoid electric shock or wiring damage. If problems arise, have professionals perform repairs.

9.Content Playback Restrictions:

Do not play full-brightness, full-white images on the indoor LED display screen for more than half an hour, to prevent excessive current, overheating of power cords, damage to LED lights, and reduced display lifespan.

10.Regular Inspection:

Periodically check the security of mounting points. If looseness occurs, adjust promptly, reinforce, or replace hanging hardware.
