Precautions for using LCD vertical advertising machine
1. Do not expose the machine to rain or sun for a long time to avoid affecting the normal use of the machine function.
2. Please do not insert or remove the card when the machine is turned on. The operation should be performed after the machine is turned off.
3. Do not disassemble or repair the LCD vertical advertising machine by yourself to avoid high-voltage electric shock or other dangers. Professional maintenance personnel should be asked to complete all maintenance work.
4. Before cleaning the LCD vertical advertising machine screen, please unplug the power cord first to ensure that the advertising machine is in a power-off state. Wipe it gently with a clean, soft cloth without thread ends. Do not use spray directly on the screen.
5. Please read the instructions carefully before inserting and removing the CF card. If the CF card cannot be inserted, do not insert it hard to avoid damaging the CF card pin. When this problem occurs, you need to check whether it is inserted in reverse.
6. If the device does not work for a long time, please open the anti-theft lock at the card insertion point to turn off the 220V power supply or unplug the power supply directly.
7. Please do not block the ventilation holes and audio holes on the shell of the LCD vertical advertising machine, and do not place the advertising machine near the radiator, heat source or any other equipment that may affect normal ventilation.
