1. Precautions for product use
●The packaged products should be placed in a dry environment, and the humidity should be controlled below 60% RH. If it exceeds 60% RH, it needs to be dehumidified, especially in spring or mildew weather. The ambient temperature should be controlled below 30℃, and if it exceeds 30℃, it needs to be cooled down;
●The product will be stored for more than one month and it will take 6 hours of aging before use before it can be used normally. The aging method is: full brightness setting is 10% 1H, full brightness setting is 30% 1H, full brightness setting is 60% 2H, full brightness setting is 80% 1H, full brightness setting is 100% 1H (the brightness gradually increases and aging);
●Do not drop, push, squeeze or press the unit plate during use and transportation to avoid damaging the display screen;
●Display screens used in special environments (1. Beachside, swimming pool, bathing ground, basement, tunnel; 2. Chemical environment, sulfurized environment, halogen environment; 3. Sand and dusty environment; 4. Strong ultraviolet environment; 5. Strong electromagnetic field environment; 6. Ambient less than -20 degrees and greater than +40 degrees), please inform us before placing an order;
●People who come into contact with the product must wear electrostatic bracelets and electrostatic gloves, and various tools must be strictly grounded during the assembly process;
●Before unboxing, confirm whether it is a module of the same batch. Products with different batch numbers cannot be installed on one screen, otherwise color blocks (mosaics) will occur on the display;
●When installing the module, please be careful to check the correct wiring of the power port. The positive and negative poles must correspond to each other before power is turned on. If the positive and negative poles are connected in reverse, the module will be burned and the power must be cut off in time to avoid fire. Use a special switching power supply for LED display screens. The limit working voltage of the module is less than 5V, and it must not be directly connected to 220V, otherwise the entire screen module will be burned;
●When wiring the power supply, make sure that the terminal connector screws are tightened to prevent loosening and causing large contact resistance to cause burning wire or product damage. M4 screw torque 6-8 Kgf/㎝², M3 screw torque 4-6 Kgf/㎝²;
●It is prohibited to assemble the unit board when power is turned on. The unit board should be assembled on the wall when the main power input is disconnected. It is not allowed to assemble the power cord and signal cord with insertion;
●In the process of lighting, people are prohibited from touching and touching the LED display screen to avoid electrostatic breakdown of LED lamps, chips and other components caused by human friction;
●The installation angle and height must be appropriate, and sharp corners must be packaged to prevent the hard shell from harming the human body;
●Within the relative humidity range of 10% to 65%RH, it is recommended to turn on the display once a day, and use it normally for more than 4 hours each time to remove moisture on the display; if the humidity is higher than 65%RH or the weather is back, the use environment needs to be dehumidified. It is recommended to use it normally for more than 8 hours a day, and close the relevant doors and windows at night to prevent the display from getting damp and causing adverse effects.
●When the display screen is not used for a long time, it is necessary to reduce the brightness of the entire screen by 50% in advance for 12 hours to play and preheat for "dehumidification" 12H to avoid damage to the light tube after the LED screen is damp
●To ensure the service life of the LED, please do not display only still images or text for a long time, which will cause severe attenuation of the brightness of the lamp or
If the batch dead light problem is caused, please play the scrolling screen or text.
●When disassembly and assemble, no sweat or other liquids drip on the display screen. If there is any drip, alcohol is required to clean the drop position of the product to prevent liquid corrosion and damage to the product.

10. Entire screen acceptance requirements and methods
●Screen brightness: Turn the screen to fully lit, adjust the brightness efficiency of the test software to 80% on the computer, and use a light gun to measure the brightness of the screen within 10 minutes. When measuring brightness, the light gun is required to be aimed at the screen. *** is to measure the time the light gun can keep level with the screen, ensure that the black position of the observation window covers more than 16 pixels, and adjust the focal length so that you can clearly see the luminous point before measuring and reading;
●Visible angle: When measuring, the person stands at 160° on the left and right of the screen, and watches at 70° on the bottom of the screen (i.e., the vertical viewing angle of the screen is 140°). The screen requires no obvious dark spots or obvious dark blocks;
●Grounding: The switch power supply shell, box and screen structure are correctly grounded, the grounding point is correctly marked, and the grounding resistance is required to be ≤ 10 ohms, and inspection is carried out every six months;
●Lightning protection treatment: The building requires lightning rods or lightning belt facilities and is effectively grounded. The distribution box is required to have a distribution box and a surge protector. The lightning protection facilities are inspected every six months.
