First, matters needing attention

1. Unplug the cable while the power is off.

2. Ensure that the electrical part is stable and safe. The interval between opening and closing should not be less than 6 seconds.

3, the LCD screen is glass fragile products; any drop, knock and strong vibration may cause the glass to rupture; it is forbidden to press the display area of the LCD screen hard;

Do not squeeze the LCD screen and frame when installing; pay attention to the overall flatness of the LCD screen, avoiding external forces causing the LCD screen to “bend” and “distort”.

4. Since the visual characteristics of the LCD screen may change depending on the viewing angle, the appropriate viewing angle of the user should be fully considered during assembly.

Adjust the optimal viewing angle position of the LCD screen.

5. During use or storage, be careful of the surface polarizer of the LCD screen to avoid being scratched by hard objects. (It is strictly forbidden to place hard objects on the LCD screen)

6. In the display driver circuit, the inverter part has high voltage. Please avoid contact during operation to avoid unnecessary damage.

7. The LCD screen works and stores below the specified temperature and temperature range, which may cause liquid crystal to crystallize and cause irreparable damage;

If it is operated and stored at a temperature higher than the specified temperature and temperature range, the liquid crystal may become an isotropic liquid and the liquid crystal state cannot be restored.

Please save and use within the allowable temperature range of the display

8, the product is a wide voltage DC input, suitable for DC 12V switching power supply error is not greater than +/- 1V.

9. There are electronic components in the circuit drive part on the back of the LCD display. In the process of design, assembly and disposal, it should avoid squeezing and damage. Otherwise, the dysfunction of  the LCD screen may be caused by damage to the electronic components.

10. Precision instruments are not allowed to be opened, disassembled or modified.
