4. Maintenance

4.1 Precautions

1. Before maintenance, the power supply must be shut off to prevent electric shock and injury, and avoid short circuit of the live parts of the PCB board against the metal frame.
2. Please pay attention to protect the LED panel surface when using the front maintenance tools, and do not damage the module surface.
3. Please pay attention to anti-static measures when using the front maintenance tools, and wear anti-static gloves to prevent static damage to LED.
4. Pay attention to take out the module vertically to avoid damage and falling of LED lamp due to collision with edge of adjacent module.

4.2 LED Display Panel Maintenance

This product supports front LED panel maintenance. The tools required for front maintenance are vacuum front maintenance tools, as shown below:

- This product supports the front maintenance tool for the modules panel, as shown in the following figure.

2	Sucker	Seal between tool and LED panel
3	Power input interface	Connect the power cable
4	Handle	Handling
5	Turn on/off	Power on: “—”; Power off:“O”

● The front maintenance process as follows:

Step 1: Turn off the power supply for the screen

Step 2: Connect the AC power cable to the tool, align it with the power cable, and place it of the surface of the module. Press the on key. When the switch label is downward, the tool starts to pump air.

(ON)

Step 3: After about 3-5 seconds of pumping air, the vacuum suction tightly adsorbs the module, and forcefully pulls the module out vertically. Hold the module with one hand to prevent it from falling off. Make sure that the module does not touch the adjacent lamp board when pulling out, so as to avoid collision and damage to the lamp bead.
