Safety Instructions
The device must be installed, serviced and maintained by a trained professional with necessary safety knowledge and skills. Before installation, be sure to carefully read and implement the safety instructions specified in this manual.
- The power supply meets the requirements indicated on the device, and the power voltage is stable. The power supply of the splicing system (such as decoder, video wall controller, matrix, and splicing screen) must use an appropriate UPS or a voltage stabilizer whose normal power is greater than 1.5 times the power used by the splicing system. The splicing system must use a three-phase socket with a protective grounding wire.
- The splicing system shall be powered in phase with the image controller and control PC, but out of phase with high-power equipment such as high-power air conditioner.
- All the grounding devices must be securely grounded, and the grounding wire of all devices must be connected to an equipotential socket to ensure that there is no voltage difference between the devices. The grounding bus shall use multi-core copper wires, and cannot be shorted or mixed with the neutral wire of the power grid.
- The operating temperature for the device is 0°C to 40°C. Operation out of this range may cause device failure. The operating humidity is 20% to 80%. Use a dehumidifier if necessary.
- To install the device on the ground, make sure that the ground is flat and solid with a strong load-bearing capacity first. The rack is generally installed on the cement floor. To install it on a floor, reinforce the floor first.
- Wiring troughs for strong and weak currents must be strictly separated. A short wiring distance is preferred. The connection of wiring troughs must be smooth without burrs and sharp corners. The wiring troughs must be properly grounded and shielded.
- Keep the maintenance channel well ventilated. Keep the device at a distance of around 3m from the air conditioning.
- Do not open the cabinet as there are high voltage components inside.
- Handle with care during transportation and installation. Do not knock, squeeze or carve the screen with hard objects. User shall assume total responsibility for damages caused by improper user operations.
- Leave at least 0.6mm space around the device for heat dissipation.
- Use the device in a clean environment. The dust concentration shall meet the office environment requirements.
- Do not leave the device in standby for a long time. When you do not use the device for a long time, disconnect the power.
- Do not switch on and off frequently. The interval between on and off cannot be less than 3 minutes.
- Keep liquid of any kind, sharp objects, metals from entering the vents or contacting the connectors. Otherwise, it may cause electric shock, short circuit or device failure. Keep away from children.

Maintenance
In daily use, please perform maintenance operations as follows.
- Do not open the cabinet yourself
Do not open the cabinet yourself. The high voltage inside will endanger your personal safety. - Keep away from fire and water
Do not place the device near candles, water, etc., otherwise the device may be damaged. Such damage is not covered by the warranty. - Do not touch the screen
Do not touch the screen, such as poking or pressing the screen with your fingers or sharp objects (e.g., pen tip, tiny hard particles on the cleaning cloth), it may result in a broken screen, liquid crystal leakage, etc. Such damage is not covered by the warranty. - Do not assemble the device yourself
Do not service the device yourself in the event of a device failure. Please seek help from the authorized personnel in time, and conduct troubleshooting under their guidance. Do not hang other LED displays around the device by yourself. Otherwise, we are not responsible for any damage to the device caused by this. - Do not insert any object into the vents or ports
Do not insert metallic and sharp objects into the vents or ports, it may cause short circuit, device failure, and electric shock. Be especially careful when children are present. - Avoid long-term operation at full capacity
Do not use the device continuously for more than 20 hours. Long time display of a stationary image will cause polarization of the liquid crystal molecules at certain pixels. If continuous operation is required, turn off the device for a ten-minute break every 20 hours, or change the display at different intervals. - Do not leave the device in standby for a long time
When you do not use the device for a long time, disconnect the power. Do not switch on and off frequently. The interval between on and off cannot be less than 3 minutes. - Precautions on cleaning the device
Be sure to use a soft and non-fiber cloth such as a dust-free cloth or a soft silk cloth. Do not use rough fibrous cloths such as linens and toilet paper, it may leave scratches on the screen. Be sure to use anhydrous alcohol or special cleaners (please purchase under the guidance of our technical support). Do not spray aqueous solutions and corrosive chemical liquids such as acetone, toluene, chloromethane, disinfectant, sulfuric acid and aqueous alcohol on the screen, it may cause dust accumulation and screen corrosion. Be sure to clean the screen from the four sides to the center to prevent dirt, dust, and other contaminants from entering the frame. - Installation environment requirements
Do not use or store the device in a damp environment for a long time, otherwise the circuit board may be oxidized and corroded, resulting in device failure. The operating temperature for the device is 0°C to 40°C. Operation out of this range may cause device failure. The operating humidity is 20% to 80%. Use a dehumidifier if necessary. The device and the video output devices connected to it must be co-grounded, otherwise static electricity will occur and interfere with the video signal, or even static surges may occur and damage the interfaces. Such damage is not covered by the warranty. - Dust regularly
To ensure the device performance, please dust the device regularly and keep the maintenance channel clean. Dust accumulation will cause abnormalities such as unclear images and black screen on the edges. And users shall clean the device regularly to avoid such abnormalities. Such damage is not covered by the warranty.
