Operating humidity range: 10%RH - 65%RH. If the humidity exceeds the standard, the environment must be dehumidified before normal use.

Storage overdue processing

Products stored for more than one month must undergo a 6-hour aging process before normal use. The aging process is as follows: 10% full brightness for 1 hour, 30% full brightness for 1 hour, 60% full brightness for 2 hours, 80% full brightness for 1 hour, and 100% full brightness for 1 hour (brightness gradually increases during aging ) .

Dust prevention requirements

Indoor products without a protection rating or IP30 should not be exposed to dusty environments, such as studio renovations or alterations, requiring special protection. LED displays should not be installed during special renovations.

Corrosive gases

Corrosive gases in environments containing salt or acid can cause corrosion, crystallization, and leakage of electronic components.

Electromagnetic radiation protection

The display screen should not be placed in an environment where electromagnetic radiation or radio frequency radiation exceeds a field strength of 5V/m.

Avoid strong light exposure

Strong light can affect the display effect of the screen and shorten the product's lifespan. It should be avoided to install it in a direction where it will be exposed to direct sunlight for a long time.

away from water sources

Indoor products have low protection levels, and water conducts electricity, which can cause short circuits and damage circuit components. Therefore, they should be kept away from water sources.

Static electricity hazards, prevent lightning strikes

The metal components of the screen, the casing of the switching power supply, and the enclosure must be properly grounded. Note that the grounding resistance should be ≤10Ω and the neutral-to-ground voltage should be ≤2V. This is to prevent static electricity from damaging electronic components and to avoid leakage current from harming the human body .

Personal injury

The installation angle and height of the display screen must be appropriate, and sharp edges and corners must be covered to prevent injury to the human body from the hard casing.

Special environment

Display screens for use in special environments (1. seaside, swimming pool, bathhouse, basement, tunnel; 2. chemical environment, sulfur environment, halogen environment; 3. dusty or sandy environment); 4. Strong ultraviolet radiation environment; 5. Strong electromagnetic field environment; 6. Environment with temperatures below -20 degrees Celsius and above +40 degrees Celsius. A review process is required before placing an order.

Disassembly and transportation process

Do not drop, push, squeeze, or press the unit board to avoid damaging the display screen;

Disassembly and maintenance of liquid protection

During disassembly and assembly, sweat or other liquids must not drip onto the display screen. If any liquid does drip, the affected area must be cleaned with alcohol to prevent corrosion.

Install torque control

supply , ensure the terminal screws are tightened to prevent loose connections, which could lead to high contact resistance, causing wire burnout or product damage. M4 screw torque is 6.0-8.0 Kgf.cm , and M3 screw torque is 4.0-6.0 Kgf.cm.

Live work is prohibited

It is forbidden to assemble the unit boards while they are powered on. The main power input should be disconnected before assembling the unit boards on the wall. It is not allowed to assemble them with power cords and signal cables inserted.

Do not touch

Personnel are prohibited from touching or manipulating the LED display screen to prevent static electricity generated by friction from damaging the LED lights, chips, and other components.

Loader selection

by the official website of Qiangli Jucai and the loading program in the one-click debugging section of the official website are required to avoid performance anomalies during the debugging process.

Parameter settings

The refresh rate must be set according to the value specified in the datasheet to protect the normal lifespan of the lamp .

Playback Control

Please do not display static images, text, or fixed backgrounds for extended periods, as this may cause severe brightness degradation of the lamps or lead to mass lamp failures. Please use scrolling images or text instead.

Usage Environment

Indoor screens must not be used in outdoor or sub-outdoor environments.

Environmental inspection

A temperature and humidity meter should be installed at the display screen installation site to monitor the surrounding environment in a timely manner. After heavy rain, the inside of the display screen should be checked for moisture, water droplets, or condensation.

Product moisture-proof usage requirements

Fixed installation display screen

When the relative humidity of the application environment is in the range of 10% to 65%RH, it is recommended to turn on the display screen once a day and use it normally for more than 4 hours each time to remove moisture from the display screen.

If the relative humidity of the application environment exceeds 65%RH, dehumidification of the environment is required. It is also recommended to use the device for at least 8 hours per day, and to close relevant doors and windows at night to prevent the display from getting damp and causing malfunctions.

If the display screen has not been used for a long time, it needs to be preheated and dehumidified for 8 hours before use to prevent damage to the lamps due to moisture. The dehumidification modes are: full brightness setting 10% for 1 hour, full brightness setting 30% for 2 hours, full brightness setting 60% for 2 hours, full brightness setting 80% for 2 hours, and full brightness setting 100% for 1 hour (brightness gradually increases with aging ) .

Rental display screen

After each use, it must be immediately packed into the flight case and the case lid must be closed and sealed tightly.

Please place at least 50g of desiccant or a moisture-absorbing bag in each flight case.

Within a relative humidity range of 10% to 65%, remove the device and play videos for at least 2 hours every half month. If the relative humidity exceeds 65% or during humid weather, remove the device and play videos for at least 2 hours every week. After all videos have been played, immediately place the device in the flight case and seal it for storage. (Please check whether the desiccant or moisture-absorbing bag inside the case has expired. It needs to be replaced every 2 months. In addition, adding more desiccant can improve the dryness inside the case.)

If the display screen is not used for an extended period, the overall screen brightness should be reduced by 50% and the video played for 12 hours to preheat and dehumidify it for 12 hours. This prevents the LED screen from getting damp and damaging the lamps.

When renting out the screen, avoid getting water on it. If water does get on it, make sure to blow the water off the screen, let it sit for 2 hours, and then turn on the screen for 2 hours to allow the heat from the LEDs and ICs to evaporate the water.

It is strictly forbidden to use indoor rental screens as outdoor rental screens, especially in open-air environments;

Avoid performing construction work on the installed LED display screen.

After the LED display screen is installed, no further construction work is allowed to prevent the LED display screen from being affected by high current impact and dust, such as by the operation of equipment like electric welding and electric saws.

1. When handling LED light boards and panels, precautions must be taken against static electricity. The following effective protective measures should be taken:

Wear a grounded anti-static wrist strap or anti-static gloves ;

The screen should be strictly grounded, with a grounding resistance of ≤10 ohms, and should be inspected every six months.

2. When cleaning the surface of the light panel, do not use unknown chemical liquids. You can use a clean, dust-free or clean, damp cloth to wipe it gently.

3. The distribution box must be equipped with surge protectors and other protective facilities.
