1. Do not hit with metal objects.
Usually the HMI will be covered with a layer of glass to protect the screen and make it easy to touch. However, the glass is fragile, do not hit the screen with metal objects during use, it is easy to cause the glass to be scratched or broken.
2. Avoid squeezing the screen with heavy objects.
The HMI is surrounded by a circuit board to control the touch. If you press a heavy object, it is easy to damage the circuit board, or the HMI is crushed, which impairs the touch accuracy and affects the use.
3. Dust regularly.
The frame and glass of the HMI will drop a lot of dust if it is used for a long time, and if it is not cleaned regularly, the touch response will be slow. Especially for outdoor HMIs, environmental factors have a great influence on them. Cleaning and maintaining the environment around the HMI of the outdoor unit from time to time, such as cleaning up the garbage and sewage near the machine; Keep the ground level, etc.
4. Turn off the power when not in use.
When the HMI is not in use for a long time, it is recommended to cut off the power supply and let the HMI stay stationary, which can prolong the life of the HMI.
5. Do not open the HMI housing lightly.
There are many circuit boards in the HMI, and their functions and arrangements are already arranged at the time of production and installation. Except for special circumstances, do not open the house easily, and consult the agent or manufacturer in time if you have any questions.
6. Avoid high-voltage equipment.
When installing and using the touch frame, the strong current and the weak current must be separated and cannot walk together. Strong current radiation can interfere with the touch frame, causing a jump point or touch disconnection.
