Precautions when installing the general outdoor advertising machine (3)
Precautions for inserting and unplugging the CF card.
Before inserting and unplugging the CF card of the Outdoor LCD Advertising Machine, please read the equipment manual carefully. If the CF card cannot be inserted, do not insert it forcibly, so as not to damage the CF card pin. If this problem occurs at this time, you need to check whether it is inserted backwards or whether there is any foreign object blocking the socket.
Precautions for cleaning Outdoor LCD Advertising Machines.
Before cleaning the LCD Screen of the Outdoor LCD Advertising Machine, please turn off the Digital Display and unplug the power cord to ensure that the device is in a power-off state, and then gently wipe it with a clean, soft, lint-free cotton cloth that is not easy to remove fluff. Use the spray directly on the screen.
At the same time, if the Outdoor LCD Advertising Machine fails, non-professional maintenance personnel should not disassemble or repair the Outdoor LCD Advertising Machine by themselves to avoid high-voltage electric shock or other dangers. Professional maintenance personnel should be asked to complete all maintenance work.
